Creating Custom Human Body Diagrams: Methods and Tools
For those looking to create personalized human body diagrams, several methods are available. How can you create custom anatomical illustrations tailored to your specific needs?
1. Deriving from Raster Images
This method involves using pre-existing raster images (typically in PNG format) that already include commonly used organs. Text and lines can be added using most graphics editors, making it an accessible option for those with limited design experience. While this approach is straightforward, it offers limited customization in terms of organ selection and placement.
2. Building “From Scratch”
For more flexibility, you can start with a “plain” body image and add individual organ images as needed. This method requires a graphics editor capable of handling transparent images to avoid white squares around the organs when pasting them onto the body template. While more time-consuming, this approach allows for greater customization and precision in organ placement.
3. Using Vector Templates
Vector templates offer the highest level of customization and scalability. Using software like Inkscape, you can create highly detailed and fully customizable diagrams. This method is ideal for professional-grade illustrations and allows for easy resizing without loss of quality.
Regardless of the method chosen, it’s essential to consider the intended use of the diagram and the level of detail required when selecting a creation approach.

Internal structure of human organs: basic structures and functions
Learn all about the internal structure of the main human organs: heart, lungs, liver, kidneys and others.
Understand how they function, what parts they have, and how they relate to each other. All information on our website.
The human body is a complex system, which consists of a set of organs and tissues, each of which performs its own unique function. In order to understand how our body works, it is necessary to know the basic structures and functions of each organ.
The human body consists of organs and tissues, each of which has its own unique internal structure. The study of this structure allows you to understand what functions the organs perform and how they are related to each other.
It is important to take into account that each organ affects the work of other organs and the whole organism as a whole. Therefore, knowledge about the internal structure of organs will allow you to more fully understand the processes occurring in the body and make more informed decisions regarding your health.
The heart is the main human circulatory organ that provides continuous blood flow to all organs and tissues of the body.
It consists of four cavities: the right and left atria and the right and left ventricles. The heart contracts and relaxes in a certain rhythm, which ensures normal blood flow.
Arteries are tubular structures that carry blood from the heart to organs and tissues. There are muscle cells in the walls of arteries that control blood pressure and regulate blood flow in every organ and tissue.
Veins are tubular structures that carry blood from tissues and organs back to the heart. They have valves that prevent the backflow of blood and ensure that it only flows in one direction.
Capillaries are the smallest blood vessels that connect arteries and veins. They provide the exchange of substances between the blood and cells of the body, and also participate in the regulation of heat transfer in the body.
The human respiratory system consists of many organs: the nasal cavity, larynx, trachea, bronchi and lungs. The nasal cavity performs the function of filtering, moistening and warming the inhaled air, where the mucous membrane contains many small hairs – keels, which throw pollution out.
The larynx, located at the top of the throat, connects the nasal cavity and the trachea. The trachea is a tube that connects the larynx and bronchi and then splits into two separate bronchi, each leading to a lung.
The main function of the respiratory system is to supply oxygen to the body and remove carbon dioxide. Breathing occurs automatically, without effort and volitional control. During inhalation, the ribs expand and the diaphragm contracts and descends, increasing the total volumetric capacity of the chest. Air containing oxygen passes through the nose or mouth, then through the larynx and trachea, and finally enters the lungs through the bronchi. In the lungs, oxygen passes into the bloodstream, and carbon dioxide is excreted from the body.
In fact, breathing is an integral part of life. The function of the respiratory system not only supplies oxygen to the body, but also purifies its blood by removing decay products and waste gases. In addition, breathing is an important part of our physical health, increasing our stamina and helping us cope with stress.
To maintain a healthy respiratory system, it is necessary to maintain a healthy lifestyle, including regular outdoor walks, exercise, and not smoking.
The digestive system is one of the most important systems of the body, which performs a number of important functions. Its main task is to process the food that we eat into elements that our body can absorb and use. In addition, it also controls the excretion of waste products and toxins from the body.
The digestive system consists of several parts, each of which performs its specific function. It includes the mouth, pharynx, esophagus, stomach, small and large intestines, rectum, and anus.
There are four main processes in the human body during digestion: mechanical processing, chemical processing, absorption of nutrients and removal of indigestible residues.
Q&A:
What are the main structures that make the digestive system work?
The main structures that ensure the functioning of the digestive system are the stomach, liver, pancreas, intestines and anus.
They perform a variety of functions, from processing food and excreting bile to disposing of body waste.
What structures make up the nervous system and how do they work?
The nervous system consists of the brain, spinal cord, nerves and synapses. It is responsible for the transmission of information between different parts of the body and ensures the coordination of movements and the regulation of internal organs. Nerve impulses are transmitted through synapses, the points of contact between nerve cells.
What structures form the blood and what is their role in the body?
Blood is formed in the bone marrow and consists of red and white blood cells, platelets and plasma. Red blood cells carry oxygen from the lungs to tissues, white blood cells protect the body from bacteria and viruses, and platelets are involved in blood clotting. Plasma contains water, nutrients, and other important compounds such as antibodies.
How are the lungs arranged and what role do they play in breathing?
The lungs are made up of three main structures: bronchi, bronchioles and alveoli.
They provide oxygen to the body and remove carbon dioxide. When you inhale, oxygen passes through the bronchi and bronchioles to the alveoli, where it is absorbed into the blood. When exhaling, carbon dioxide is removed from the air alveoli and exhaled through the nose or mouth.
What structures make up the genitourinary system and how do they work?
The genitourinary system consists of the kidneys, ureters, bladder and urethra. It is responsible for the elimination of body waste and the regulation of water and electrolyte balance. The kidneys filter the blood, removing excess water and metabolites from the blood, which are then excreted through the urinary tract.
What are the main structures of the skin and what role do they play?
Skin consists of three layers: epidermis, dermis and subcutaneous adipose tissue. It performs protective, regulatory and sensitive functions. The epidermis contains keratin, which prevents deformation and protects the skin from harmful effects.
The dermis contains collagen, which improves the elasticity and firmness of the skin. Subcutaneous adipose tissue contains fat, which moisturizes the skin and provides thermal insulation.
What is the role of bones in the body and how are they arranged?
Bones make up the skeleton and perform several functions, such as maintaining the shape and protection of internal organs, providing movement and participating in calcium metabolism. Bones consist of bone marrow, epiphyses and diaphyses. The bone marrow produces blood, the epiphyses provide limb movement, and the diaphysis provides shape maintenance.
How is the heart arranged and how does it work?
The heart consists of four chambers: the right atrium and ventricle, the left atrium and ventricle. It is responsible for the circulation of blood throughout the body. Blood from the right atrium enters the right ventricle, then is expelled to the lungs, where it picks up oxygen and returns to the left atrium.
Then the blood enters the left ventricle and then to all other parts of the body.
Internal structure of the urinary system
Kidneys
The kidneys are the main organ of the urinary system, filtering the blood and removing its metabolic products from the body. They contain several structural units – nephrons, which provide the function of the organ.
Nephron is a complex system of tubules and capillaries that are involved in the blood filtration process. Capillaries located in the nephrons allow the transfer of filtered products to the tubules, which then pass them to the ureter.
Ureters, bladder, urethra
Ureters are the tubes that connect the nephrons to the bladder. The bladder is an organ that temporarily stores urine before it is expelled from the body through the urethra.
The urethra is the conduit that passes through the prostate gland in men and leads from the bladder to the outside of the body.
In women, the length of the urethra is shorter, and its opening is closer to the anus.
A large volume of urine in the bladder causes a feeling of urination, which in turn signals the urethra to contract and expel urine from the body.
Functioning of the urinary system
Blood enters the kidneys through an artery located near the spinal column. In the nephrons, blood passes through a separate system of capillaries that filter waste products and water from the blood.
The filtered fluid, called primary urine, travels through the ureters to the bladder, where it is temporarily stored. The urethra removes urine from the bladder and the body as a whole.
The urinary system is important for clearing the blood of products that can only be excreted through urine, as well as for controlling fluid levels in the body.
Nervous system
Structure of the nervous system
The nervous system is a complex mechanism that is responsible for the transmission of signals in the body.
It consists of the central and peripheral nervous systems. The central nervous system includes the brain, spinal cord, and spinal nerves. The peripheral nervous system consists of all the nerves that are located outside the central nervous system. Together they ensure the transfer of information between organs and tissues.
Functions of the nervous system
The nervous system has a number of functions, including detecting and responding to changes in the body’s internal and external environment. In addition, it controls motor activity, coordination of movements, the state of the psyche, as well as many other processes in the body. The nervous system is also responsible for processing information that comes from the senses.
Nervous system disorders
Nervous system disorders can lead to various diseases such as migraine, Parkinson’s disease, depression and epilepsy. These diseases can have various causes, including heredity, trauma, or system malfunction.
Treatment for such conditions may include medications, therapeutic exercises, and other methods.
Endocrine system: the most important system in our body
Description
The endocrine system, also called the internal excretory system, is one of the most important systems in our body. It includes hormones, glands, and other components that help control bodily functions. Hormones released by the glands include adrenaline, thyroid hormones, and insulin.
Functions
The main function of the endocrine system is to regulate the functioning of various organs and tissues in the body. It is also responsible for controlling the growth, development, and function of the gonads, as well as regulating blood glucose levels. In addition, the endocrine system helps maintain the balance of fluids and electrolytes in the body.
Glands
Glands are the main components of the endocrine system. They are located in various parts of the body and are responsible for the production and release of hormones into the blood.
Some of the most important glands include the thyroid, pancreas, and pituitary.
Malfunctions and Disorders
If the endocrine system does not function properly, it can lead to various disorders such as diabetes, hypothyroidism and hyperthyroidism. A malfunctioning endocrine system can also lead to elevated hormone levels, which can lead to various illnesses and diseases, such as breast or prostate cancer.
Conclusion
The endocrine system plays an important role in maintaining the normal functioning of our body. The glands secrete the most important hormones that help regulate the functioning of organs and tissues, and also affect the growth and development of the body. However, if the system stops functioning properly, it can lead to serious disorders that can lead to health complications.
Muscular system
Basic structures
The muscular system consists of skeletal muscles that are attached to the bone and provide movement of the body, smooth muscles that are located in organs and act automatically, and the cardiac muscle that ensures the rhythmic work of the heart.
Skeletal muscles are made up of muscle fibers connected together through tendons and ligaments. Each muscle fiber contains sarcomeres, microscopic structures that are responsible for muscle contraction.
Smooth muscles do not have such an obvious structure as skeletal ones, and can contract autonomously, without the participation of volitional mechanisms. Well developed in the digestive, respiratory and excretory systems.
Functions
The main function of the muscular system is to move the body. Skeletal muscles can contract and stretch, resulting in movement of the limbs and torso. Smooth muscles are involved in the work of the organs of internal systems, their contraction carries out peristalsis, respiration, secretion of glands, and much more.
The muscular system is also involved in maintaining body temperature. Muscles generate heat, which helps keep the body’s core temperature stable.
In addition, the musculoskeletal system ensures the maintenance of posture and the basic shape of the body, and is also involved in the defense of the body, for example, through the facial muscles, which can express emotions.
- Summary:
- The muscular system consists of skeletal, smooth and cardiac muscles.
- Skeletal muscles provide movement of the body, smooth muscles work in the organs of internal systems.
- The muscular system is involved in maintaining body temperature, maintaining posture and protecting the body.
Skeletal system
Basic structures
The human skeletal system consists of bones, ligaments and muscles. Bones have different shapes and perform different functions. They provide support and protection for the internal organs, and are also involved in the movement and creation of blood.
Ligaments are connective tissues that hold bones together and keep them stable. Muscles are connective tissues that provide movement to bones.
Basic functions
The skeletal system performs several basic functions. It provides support and protection to internal organs such as the heart, lungs and diaphragm.
Bones are also involved in the formation of blood in the bone marrow.
The skeletal system also provides movement for the body. Muscles, connecting with bones, create a force that moves the skeleton. The bones are the immediate support points for the muscles and allow them to function effectively.
In addition, the skeletal system is involved in metabolism. Bones contain calcium, which acts as a reserve of calcium in the body.
Diseases of the skeletal system
- Osteoporosis is a disease in which the bones become more fragile and prone to fracture.
- Arthritis is a disease in which inflammation of the tissues of the joints leads to pain and limited movement.
Skeletal disease prevention includes proper nutrition, exercise, and regular medical check-ups to identify risks and start treatment on time.
Human immune system
Basic structures and functions
The immune system is a complex system of organs, tissues and cells that protects the body from infection and disease.
It consists of two main parts: the adaptive and innate immune systems.
The innate immune system is the body’s first line of defense against viruses, bacteria and other pathogens. This system includes the skin, mucous membranes, and immune cells such as neutrophils and natural killers.
The adaptive immune system is a more complex system that develops in response to infections. It includes the protein immunoglobulin, which attacks and destroys pathogens. In addition, the adaptive immune system has a memory and is able to quickly recognize and destroy repeated invasions of the same pathogen into the body.
The immune system plays a very important role in the human body, keeping it healthy and protecting it from many diseases. However, such a complex system can often malfunction, leading to autoimmune diseases, allergic reactions, and other problems.
- Innate immune system
- Skin and mucous membranes
- Neutrophils and natural killers
- Adaptive immune system
- Immunoglobulin protein

Internal structure of human organs: Skin and its functions
Basic structures of the skin
The skin is one of the largest organs in our body and performs many important functions.
It consists of three layers: epidermis, dermis and subcutaneous adipose tissue. The epidermis, the top layer of the skin, is made up of many cells that produce keratin, the protein material that makes skin tough and resistant. The dermis lies below the epidermis and contains many vessels, nerves, hair follicles, and sweat glands. Subcutaneous adipose tissue contains fat cells that provide insulation and heat retention in the body.
Functions of the skin
The skin performs many important functions, including protection from external influences, regulation of body temperature, elimination of harmful substances, participation in the metabolism and synthesis of vitamin D. The skin is also a sensory organ, through which a person receives information about temperature, pressure, pain, and other environmental stimuli.
Conclusion
The skin is a very important organ that performs many functions and plays an important role in maintaining the life of the body.
Keep it in good condition, take care of hygiene and avoid harmful effects such as burns, mechanical damage and overheating.
Eyes and their structure
Eye structure
The eye is an organ of vision, which consists of several elements. The outermost part of the eye is the cornea, which transmits light rays into the eye.
The light rays then pass through the pupil, which is the opening in the iris. The iris contains muscles that allow the size of the pupil to change depending on the brightness of the environment.
Light rays travel further through the lens, which also changes its shape to focus the image on the retina. The retina is made up of many light-sensitive cells that transmit signals to the brain via the optic nerve.
Functions of the eye
The main function of the eye is to process light rays and transmit signals to the brain for further processing. The eyes also allow you to judge the depth and distance of objects, which is important in everyday life.
In addition, the eyes are an organ that can express emotions and communicate with people around. For example, the facial muscles around the eye allow you to express joy, anger or surprise.
Diseases of the eye
- Cataract is a disease in which the lens of the eye becomes cloudy and vision is impaired;
- Glaucoma is a disease characterized by increased intraocular pressure and damage to the optic nerve;
- Macular degeneration is a disease that is associated with visual impairment in the central part of the retina, responsible for the difference in colors and image clarity.
Ear and structure
Outer ear
The ear consists of three main parts: outer, middle and inner. The outer part of the ear is the ear shell, which we used to call the auricle. This part of the ear protects the inner ear from external damage and helps collect sound waves.
Middle part of the ear
The middle part of the ear lies behind the auricle and consists of the tympanic membrane, ossicles and eustachian tube.
The tympanic membrane is the boundary between the outer and middle ear, and the auditory bones are the small bones that transmit sound waves from the tympanic membrane to the inner ear.
Inner part of the ear
Inner part of the ear lies behind the middle part and contains the hearing aid and the semicircular canals. The hearing aid consists of the cochlea and the coclear nerve, which convert sound waves into nerve impulses that are then transmitted to the brain. The semicircular canals are responsible for balance and coordination.
Conclusion
The structure of the ear is a complex and amazing system that allows us to hear and coordinate our movement. Understanding this system helps us take better care of our hearing and improve our lives in general.
The internal structure of the lips and their functions
The structure of the lips
Lips are folds of skin, subcutaneous fat, muscle fibers, mucous membranes and a special venous arrangement – capillary bulbs.
The muscular layer consists of two pairs of labial muscles, which differ in the direction of the fibers. The anterior labial muscle is responsible for lifting the upper lip and supralabial sugar bone, the occipital muscle makes the movement of the lips downward and upward. Inside the lips there is a system of sheaths in the middle of the lip, at the edges there are connective tissue plates.
Functions of the lips
Lips play an important role in many processes of our life. Through lips we eat, communicate, kiss, breathe, and also protect ourselves from environmental influences. Lips help a person become more expressive in their emotions, facial expressions and speech. Their structure ensures the stability of the mouth in different positions, allowing literally dozens of lip gestures to be performed.
The mucous membrane of the lips has a large number of specialized glands that secrete moisture that moisturizes the lips and protects them from drying out.
Structure of teeth
Teeth are hard structures made up of various tissues: enamel, dentin, pulp and cementum. They are root and crown shaped and differ in shape, size and function.
Enamel is a hard, transparent tissue that covers the outer surface of the tooth. It is composed of hydroxyapatite crystals and provides tooth strength and protection from damage.
Dentin is the hard tissue that forms the bulk of the tooth. It consists of cones connected by tubes and provides strength to the tooth and support to the enamel.
The pulp is the soft tissue inside the tooth containing blood vessels and nerve endings. It provides blood circulation and tooth sensitivity.
Cementum is a hard tissue that covers the root of the tooth and adheres to the toothbrush. It consists of collagen fibers and provides protection against corrosion and deformation.
Teeth have different shapes and functions depending on their location in the mouth. For example, incisors are used to cut food, canines are used to snatch and grab, and molars are used to chew and grind food.
The vocal cords and their functions
The vocal cords are small muscles in the throat that play an important role in sound production. They are located in the throat and fluctuate with the manifestation of the voice. Their size, shape and intensity affect how sound is produced and received.
The primary function of the vocal cords is to produce sound. Voice is produced when the vocal cords vibrate as air is exhaled from the lungs and vibrate against each other. It is extremely important that the vocal cords are healthy and without damage, as some conditions can lead to sound disturbance and voice failure.
The vocal cords play a role in a wide range of all types of communication, including speech, singing, and sound production for acting and scoring work. They can be trained to improve tone, volume, and pitch, making good vocalization and other related activities possible.
It makes sense to take care of the vocal cords and prevent potential damage whenever possible.
It is recommended to drink enough water and avoid smoking, as this can lead to a decrease in the vocal cords and cause smog and other irritations.
Vessels and their significant role in the body
Arteries
Arteries are vessels that carry blood from the heart to various organs and tissues of our body. They have a unique structure with a significant amount of muscle layers and elastic fibers to maintain blood flow. Large arteries have thick walls due to high pressure, while small arteries are thinner.
If the artery narrows, there is a problem in the passage of blood, which can lead to serious diseases such as tonsillitis or myocardial infarction. Therefore, it is important to monitor the health of the arteries.
Veins
Veins are blood vessels that carry blood back to the heart. Veins are characterized by thinner walls and less developed muscle layers, so blood moves more slowly compared to arteries.
The venous system includes a less precise system of anchors that allow blood to be retained in the upper body.
The venous system has valves that prevent backflow of blood. Certain diseases, such as varicose veins, can make it difficult for the normal flow of blood in the veins, which can lead to more serious conditions.
Capillaries
Capillaries are the thinnest vessels in the human body. They connect the arterial and venous systems, allowing blood to enter various tissues and organs. Capillaries are blood vessels that control the distribution of oxygen and nutrients. They are also responsible for transporting carbon dioxide and waste products from the body. Capillaries are characterized by very thin walls, allowing blood to flow efficiently through them.
Thus, vessels play an important role in the body, carrying blood and transporting nutrients and oxygen to cells and tissues. They also help to transport waste and exhaust carbon dioxide necessary for removal in the opposite direction. Therefore, it is necessary to monitor the health of blood vessels, which contributes to the proper functioning of our body as a whole.
Pulmonary ventilation and its role in the functioning of the respiratory system
Pulmonary ventilation is a process associated with the exchange of gases between the lungs and the atmosphere. This is the most important process that ensures the supply of oxygen to the body and the utilization of carbon dioxide, which is formed in the process of metabolism. The air that enters the lungs during inhalation contains about 21% oxygen. When exhaling, a person releases about 16% of the oxygen that the body needs.
The regulation of pulmonary ventilation occurs through the activity of the nervous system, as well as humoral regulation, when certain hormones in the blood regulate breathing. It is important to note that although pulmonary ventilation occurs automatically, it can also be controlled by consciousness, for example, during yoga and meditation.
Alveoli, microscopic vesicles located at the end of the bronchial tree, play an important role in the process of respiration.
It is in them that gas exchange occurs between the lungs and the blood. From the alveoli, the blood receives oxygen and dumps excess carbon dioxide, which is released through the lungs into the environment during exhalation.
In addition, it is worth noting that pulmonary ventilation plays an important role in the functioning of not only the respiratory system, but also in the functioning of the body in general. A sufficient level of oxygen is necessary not only for the vital activity of the lungs, but also for other body systems, such as the cardiovascular system and the brain.

Human internal organs
The internal organs are hidden from view and it is sometimes difficult to determine which organ the strange sensations or pains refer to. Today we will deal with the location of the internal organs of a person.
Human anatomy internal organs
Basically, the internal organs of a person are divided into three areas:
- abdomen
- chest cavity
- pelvic area
Also internal organs include:
- brain
- thyroid gland
- language
- larynx
- diaphragm
Coordinated work of all internal organs, invisible to the eye, ensures the normal functioning of the human body.
Description of single human internal organs
Speaking specifically about each organ, we can briefly list the following:
- The brain is the central organ of the entire nervous system, which coordinates the work of all body systems, on average, the weight of the brain is from 1.2 to 1.4 kg.
- Language – necessary for touch and taste perception, processing of writing and speech.
- Thyroid gland – with a weight of only 20 g, it performs the most important functions for ensuring metabolism and maintaining homeostasis.
- The diaphragm, being on the border between two cavities, performs a supporting function, provides working pressure in the underlying organs, and also participates in the respiratory process.
Human thoracic organs: location
Positioned as follows:
- The heart is the central element of the cardiovascular system, the lungs are located to the right and left of it, in most people the heart is located to the left of the center line of the chest, but there are exceptions.
- The lungs are the central organ of the respiratory system, occupying almost the entire space of the chest, with their base resting on the diaphragm.
- Bronchi – are tubular processes of the trachea, despite the fact that the organ is a pair, the sizes of its parts are not the same. They supply the lungs with the oxygen necessary for life.
- Thymus – one of the most important organs responsible for immunity, is small in size, located in the upper part of the chest cavity.
Human abdominal organs: location of
Positioned as follows:
- The stomach is located on the left side under the diaphragm, it begins the process of primary digestion of incoming food, it is he who gives a signal about the onset of satiety.
- The pancreas – in accordance with the name is located below the stomach and is responsible for the production of enzymes necessary for the digestion of food, and also provides fat, protein and carbohydrate metabolism.
- The spleen is located on the left behind the stomach, it is responsible for hematopoiesis and immunity.
- The kidneys are located symmetrically in the lower part of the peritoneum and are responsible for the urinary excretion function.
- The liver is located on the right under the diaphragm and is divided into 2 parts, this organ is responsible for removing toxins, poisons, removing unnecessary elements, is responsible for blood formation during pregnancy and much more.
- The gallbladder is located below the liver and incoming bile accumulates in it, the maximum length of the organ is 10 cm, it resembles a pear in shape, the accumulated fluid enters the intestine through the bile ducts.
- The intestine is located in the lower part of the abdomen and consists of two parts – the small and large intestines, in which useful substances are absorbed and enter the bloodstream.
- Appendix – a small appendage of the caecum in length reaches 12 cm, diameter less than 1 cm, it performs a protective function, preventing the development of diseases of the intestinal tract.
Human pelvic and pelvic organs: location
Positioned as follows:
- Bladder – urine accumulates in it before urination occurs, it is located in the lower part in front of the pubic bone
- The uterus is located above the bladder, the usual size is about 7 cm, it is responsible for the reproductive function in women
- Ovaries is a female organ in which the germ cells necessary for procreation mature
- Prostate gland — the male organ located under the bladder, is responsible for the production of secretory fluid
- Testicles – the male reproductive organ located in the scrotum, they produce sex cells and hormones
