The human body is made up of various organs that perform one function or another. The eyes , for example, allow us to see the world around us – the shape of objects, colors, people, and so on. Those who are not interested in anatomy do not know that the eye has a perfect structure and provides vision in three dimensions and with the highest sharpness …
Some people do not like it when they look into their eyes, and there is an explanation for that – they are, as they say, “the mirror of the soul “, in order to look into it, you first need to create a trusting relationship …
Well, what are we all about eyes ?! There are no less interesting organs: liver, spleen, kidneys, for example. Let’s find out more about them. We bring to your attention a list of the 10 largest human organs: large and heavy internal parts of the human body – information for grade 4.

10. Large intestine
The intestine not only supplies us with nutrients, but also removes harmful substances from the body. It also helps maintain immunity. The intestine includes several sections: small intestine, rectum, large, duodenal ulcer.
Our attention is now directed to the large intestine, the large organ of our body. It is located along the perimeter of a relatively thin one, and is shaped like a frame. Its main function is to absorb water from the remaining mass and accumulate feces for their further removal from the body.
9. Spleen
The spleen is a kind of “filter” of our body. It absorbs and recycles bacteria that enter our bloodstream, as well as other harmful substances. Produces antibacterial bodies.
The spleen is one of the largest organs, it is very important for maintaining immunity, in addition, it contains a supply of blood – when necessary, blood enters the systemic circulation of the body.
The mysterious organ, about which not much is known, also stores iron, which is converted to hemoglobin, promotes good digestion and affects the nervous system.
8. Stomach
An important organ such as the stomach is located in the upper abdomen . It is a muscle pouch that provides a favorable environment for the breakdown and digestion of food.
The shape of the stomach changes with the age of a person, there are only 3 forms of it: stocking, hook and horn. On average, the length of the stomach along its long axis is 22-25 cm. The stomach holds 3 liters. This organ can be called part of the digestive tract chain, and, of course, an important link in it.
The stomach is located in front of the duodenum and is an extension of the esophagus. It is in this organ that the thickest area of the muscle layer is located.
7. Kidneys
The kidneys are a vital human organ . This is a paired organ located in the retroperitoneal space on the sides of the spinal column.
The kidneys make urine. The boundaries of the location of these important organs vary even within the normal range – most often the left kidney is located just above the right one. One organ weighs about 100-200 g, width – 5-6 cm, length – 11-12 cm, thickness – 3-4 cm. If the organs are noticeably deviated from these sizes, then this is a sign of pathological changes.
Anatomically, the organ looks like beans. The main function of the kidneys is excretory. It is they who form urine, together with which toxic products are washed out of the body.
6. Lungs
The lungs , like the kidneys, are also a paired organ. We owe every breath we take to this most important organ. Gas exchange takes place in the lungs, due to which our body is saturated with oxygen and removes waste carbon dioxide from the body – everyone knows this from school textbooks.
The right lung is slightly wider than the left and shorter. This structure is quite natural, because the heart is located in the left and partially central chest cavity. There is a notch on the left lung, thanks to which the heart feels quite comfortable. The left lung is a kind of shock-absorbing cushion that protects the heart from mechanical damage.
The organ resembles a cone in shape – it has a base and a top. The breathing process is quite an interesting phenomenon, because we do not even notice how we breathe. The brain itself decides how much air it needs.
However, a person himself can learn to control his breathing, for this there are even special techniques, thanks to which you can relieve stress, remove pain and even get rid of unnecessary emotions.
5. Brain
An amazing three-pound organ located inside the skull – the brain , has always attracted and attracts scientists. This body is the main one. It is he who is responsible for the work of other organs. Despite the fact that the brain is constantly being studied, much still remains a mystery in its work … People have only a superficial idea of how it works and transfers information.
The bulk of the brain is made up of cells called neurons – they create electrical impulses and transmit data. Neurons are composed of a body and processes of two types: dendrites and axons. The former receive the impulse, and the latter transmit.
The brain is responsible for emotions, creativity, memory … And this is only part of the things that are controlled by the brain. It is very important to take care of him, to solve various problems – what is not paid attention to will atrophy over time.
4. Heart
What do you imagine when you hear the word heart ? Surely something romantic, connected with feelings, pops up in your imagination …
The heart that is drawn is a symbol of love, but the organ looks different. There is a version that the symbol of the heart appeared in ancient Greece , as a symbol of femininity, beauty, and it represented nothing more than a reproduction of a woman’s breasts and buttocks.
In many cultures, this organ is considered the seat of the soul, a place where love and affection arise, but in reality it is more and more prosaic … The heart is a voluminous muscular organ the size of the fist of its bearer, weighs approximately 210 g for women, and up to 380 g for men.
When a person is born, his work does not stop even for a second. By pumping blood, the heart supplies all tissues and organs with oxygen.
3. Liver
The liver can rightfully be called a unique organ of our body, because it performs many functions. The liver is the largest organ in the digestive system. If conditions are favorable, then the organ can renew itself.
The liver is located in the right hypochondrium under the diaphragm, its weight depends on the age of the person, in an adult it is approximately 1500-1700 g.
The liver is a multifunctional organ, its most basic functions are: normalization of carbohydrate metabolism, secretion of good cholesterol, detoxification, production of some of the immune cells, etc.
2. Small intestine
The small intestine in the intestinal structure is the longest section of the digestive tract, consisting of two sections. The small intestine forms a large number of loops and passes into the large intestine. Its length is approximately 2.6 meters. Anatomically, the small intestine is divided into three sections: jejunum, duodenum, ileum.
The food mass passes through the small intestine in about 4 hours. During this time, the nutrients that are contained in the food are broken down by the enzymes of the intestinal juice into smaller components. In the small intestine, digestion also involves the active absorption of nutrients.
1. Skin
Our list is completed by an organ such as skin . It has a protective role as well as a number of other biological functions. Our entire body is covered with skin . In a healthy adult, the total area of the skin is up to 2 square meters. meters, and weight up to 6% of the total body weight.
The condition of our skin depends on factors such as: nutrition, age, lifestyle, etc. The skin includes three layers: epidermis, dermis and subcutaneous fatty tissue. Each of them includes several layers.
An interesting fact: all cosmetics that we use affect only the upper skin layer
