How many organs are there in a person and without which one can live?

There are 79 organs in the human body and each of them has its own function. For convenience, they are usually divided into categories – for example, the stomach and liver are part of the digestive system and the heart and arteries are part of the cardiovascular system. Some instruments may be part of two systems at the same time. For example, the pharynx is both a digestive and a respiratory organ. During the aging of the body, as well as as a result of illness and serious injuries, a person’s internal organs sometimes stop functioning properly. If treatment is not possible, they should be removed. In this article, we will talk about the organ systems in the human body and without which we can easily live as if nothing had happened.

You have no idea how complex the human body is!

Complete list of human organs

As mentioned at the beginning of this article, for convenience, human organs are categorized. They are grouped according to the type of work they perform: others digest food, others pump blood, others are responsible for respiration and so on.

Musculoskeletal system

The organs of the musculoskeletal system are responsible for a person’s ability to move. The basis is skeleton with all the bones – an adult has 206 of them. They are also included in this system joints, ligaments, muscles and tendons.

integrated system

This category of organs includes all the tissues of the human body. Skin and subcutaneous tissue required to protect internal organs from external influences, prevent drying, etc.

Respiratory

The respiratory system is essential for the exchange of human gases with the environment and the saturation of the blood with oxygen. This system includes bodies such as e.g. nasal cavity, pharynx, larynx, trachea, bronchi, septum and of course lungs.

Circulatory System

The organs that are part of the circulatory system provide blood circulation to the body. Complement to the circulatory system are organs that are part of the lymphatic system – it plays an important role in metabolism. Therefore, they are responsible for blood circulation heart, arteries, veins and capillaries. Participates in metabolism lymph vessels, lymph nodes, bone marrow, thymus, tonsils and spleen.

Endocrine glands

The collection of endocrine glands is necessary for the production of hormones that enter the blood or lymph vessels. Organs that produce hormones are pituitary, epiphysis, thyroid gland, parathyroid glands, adrenal glands and pancreas.

Nervous system

The nervous system is the largest and extends throughout the body. If you paint all the parts that make up the nervous system, you will need half the article, so let’s look at everything in a few words. The main parts of the central nervous system are brain, brainstem, cerebellum, spinal cord and ventricles of the brain.

human brain

Peripheral nervous system is the collection of all the nerves of the body. The sensory organs are eyes, ears, nose, tongue and all their constituent parts.

Digestive system

The organs of the digestive system are needed for food intake, digestion and excretion by the body. Food comes in first mouth with tongue, teeth and salivary glandsin chewed form, descends lengthwise esophagus and enters stomach. Also, during the process of digestion, food passes small and large intestine. It is also common to refer to the organs of the digestive system liver, gallbladder, pancreas and mesentery the latter is needed to connect hollow organs to the posterior wall of the abdomen.

urinary system

The urinary system handles fluids that enter the body. Consists of two kidneys, a pair of ureters, bladder and urethra.

Reproductive system

Once we have gone under the belt, we can talk about the reproductive system. It is, of course, very different for men and women.

Women’s internal genitals are ovaries, fallopian tubes, uterus and vagina. The list of external organs includes vulva and clitoris. It is also part of the female reproductive system fetal placenta.

The internal genitals of men are testes and their appendages, seminal vesicles, prostate and bolorethric glands. The male external genitalia are penis and scrotum.

Without which organs can you survive?

As a result of injury and illness, some organs stop functioning properly. Some of them can be surgically removed and a person can live as if nothing had happened. Unless physical activity is contraindicated for him and dietary restrictions will be imposed.

Life without a gallbladder

The gallbladder is a small sac that stores bile from the liver to digest fatty foods. Sometimes stones form inside it and the instrument must be removed. After this operation, it is very likely that you will live, but following a strict diet with low-fat foods.

Life without spleen

The spleen is necessary for a person to produce lymphocytes and bile derivatives and also provides protection against bacteria and other “unknowns”. A large amount of blood passes through the spleen and some people are very likely to be injured. Therefore, sometimes the instrument has to be removed. Without a spleen, a person is at risk of suffering from various infections but, in general, can live.

Life without kidneys

The main function of the kidneys is the excretion of fluids. Also, this paired organ is needed to filter the blood. About 200 liters of blood pass through it daily and are cleansed of harmful substances. Sometimes kidneys are removed due to illness or become donors – a person can live normally with one kidney. It is impossible to survive without both kidneys. Of course, for some time their functions can be performed by a device for artificial blood filtration, but this does not take long.

Life without appendicitis

The appendix is ​​a residual organ – it once played an important role, but it is no longer needed today. For some people, it is removed, after which you can continue to live peacefully.

Life without lungs

The lungs are needed to saturate the blood with oxygen and remove carbon dioxide. This is a paired organ, so in case of serious diseases, one of them can be surgically removed.

A person can live even with one lung.

Life without genitals

A person can live without problems without genitals – sometimes this operation is resorted to in case of serious diseases of the urogenital system or gender reassignment. There are no particular difficulties, but it is, of course, impossible to conceive a child in a natural way.

Life without colon

By the time food enters the large intestine, the nutrients have already been absorbed. This organ is needed to form and eliminate feces. This is a very important instrument, but current technology allows people to live without it.

In case of emergency, doctors can also remove the colon.

Life without stomach

In some diseases, a person can have their colon removed. In order for a person to live, his esophagus is connected to the small intestine. The length of the digestive tract is significantly reduced and this creates a number of problems. But they can be avoided by following a special diet.

Life without a bladder

The bladder is a reservoir for storing urine before it is expelled. After removal, the person can use the external tank and, although with some difficulty, continue to live.

The bladder is also completely replaceable

Life without tonsils

Above, we already understand that the tonsils are part of the lymphatic system. They are needed to maintain a strong immune system and protect the body from dangerous germs. Since they are not our only protectors, it is very likely that we will live without them.

The tonsils are also not vital organs.

Life without thyroid

The thyroid gland produces hormones that support metabolism. It is very important for the functioning of the whole organism, but sometimes it is also removed. In this case, a person for the rest of his life will depend on injections with the right hormones.

Life without eyes

In some cases, a person loses his eyes completely. They can not be replaced by anything, but there are a huge number of blind people in the world – so these organs are also not vital.

The eyes are also not vital organs.
