Let's get acquainted with unusual facts, which, perhaps, will amaze you.

Human intestine

The largest organ is the small intestine. He is four times longer than the average adult.

A normal human intestine contains about 1 kg of bacteria.

In the intestines, the Japanese have unique microbes that help to process the algae used in the preparation of sushi much better than to people of other nationalities.

The Heart of Man

The human heart creates enough pressure to spill blood at a distance of 9 m. It's no wonder that you feel the heartbeat of your heart. This blood pump carries blood all over the body quickly and efficiently, thanks to strong cardiac contractions.

The heart begins to beat from the fourth week after conception, and will not stop until the death of a person.

A new cup of blood circulates in a newborn baby. The circulatory system in an adult can hold more than 4.5 liters of blood, which the heart pumps into all tissues in one minute 75 times.

Although the heart weighs an average of 300 grams, it pumps 2,000 liters of blood through the blood vessels every day.

The heart has its own electrical impulses, which means working even outside the body, provided there is sufficient oxygen supply.

At the moment, 5% of the total blood is in your heart, 20% of the blood goes to the brain and the central nervous system, 22% goes to the kidneys.

Acidity of the stomach

The acidity of the stomach is so strong that it can dissolve the razor. However, do not take this information too seriously and specifically swallow a razor or other metal objects.

Blood vessels

Кровеносные сосуды Невероятные факты о человеческом теле. Внутренние органы.

It is estimated that in the human body the blood vessels stretch for 96,000 km.

For a visual representation, you can compare this distance with the distance around the Globe, which is 40 000 km.

That is, it is possible to decompose all blood vessels of one person in length around the Earth more than twice.

Human blood

Кровь человека Невероятные факты о человеческом теле. Внутренние органы.

Blood cells are constantly dying out and being replaced with new ones. Leukocytes (white blood cells) live from several hours to several weeks, and red blood cells (red blood cells) live from 90 to 125 days.

Only half the blood circulates through the body in the vessels. The other half in the spare "blood depots." These "depots" include the liver, spleen and skin. Subcutaneous vessels contain 10%, spleen 16% and liver up to 20% of the total blood.

About 46% of the blood is contained in the "blood depots." If there is a need to replenish blood, it throws it out of the "depot" into the blood vessels in order to continue the normal activity of the whole organism. This happens, for example, with increased muscular work or loss of blood. After the replenishment takes place, part of the blood is refilled in the skin, spleen and liver.

Recently, it was found that the predisposition to different diseases depends on the blood group. Doctors confirmed studies of geneticists.

People with the first blood group are predisposed to gastrointestinal diseases.

People with a second blood group may suffer from rheumatic diseases, allergies, bronchial asthma, diabetes, heart disease.

People with a third blood group suffer from pneumonia more often than others. They are susceptible to the development of infections. Women often have purulent mastitis, sepsis after childbirth, joint diseases and osteochondrosis.

People with the fourth blood group suffer from colds, flu and other infections.

By inheritance are transmitted not only the predispositions associated with the blood group, but also the diseases themselves. These can be intestinal infections, sore throats, pharyngitis or chronic tonsillitis.

Japanese researchers have found that the first blood group affects even the character of a person.

Protection of the stomach

You get a new "tablecloth" for the stomach every three to four days.

These mucus-like cells form on the walls of the stomach and soon dissolve because of strong digestive acids.

People who have an ulcer know how painful it can be without such a shell in the stomach.

Lung area

The area of ​​the lungs is equal to a tennis court.

In order for the blood to be saturated to be filled with oxygen, the lungs consist of thousands of tiny branches of the bronchi. They, in turn, are filled with microscopic capillaries, in which oxygen and carbon dioxide.

A large area of ​​the lungs facilitates the metabolism, and you always get the required amount of oxygen.

Women's Heart

Женское сердце Невероятные факты о человеческом теле. Внутренние органы.

A woman's heart beats faster than a man's. The reason for this is only that the mass of the female body, as a rule, is less than the mass of the male body.

However, that's not all. Male and female hearts actually can work quite differently, especially when they are injured from a heart attack and other diseases. That treatment, which is suitable for the male heart, does not always help the female.

The walls of the female heart in the left chamber predominate in characteristics with the same male walls in elasticity and fineness. The more elastic the walls in the heart chamber, the less likely the hypertensive disease.

Another feature of the female heart is a greater likelihood of stress and mental illness than men.

In medical science, the causes of diagnostic features of cardiological diseases in women are not yet clear. For example, it is not known why in women electrocardiographic examination is less reliable than in men.

Doctors for a long time have got used to consider, that cardiovascular diseases basically are shown at men. However, in recent years, statistics indicate that women suffer similar diseases in a more severe form. Lethal outcome in such cases in women 55%, and in men 45%.

Functions of the liver

Функции печени Невероятные факты о человеческом теле. Внутренние органы.

Scientists have more than 500 different liver functions. We used to remember the liver only after alcohol intoxication. But the liver is one of the most industrious and largest organs.

Here is a list of just a few of the main liver uses: bile production, erythrocyte decomposition, protein synthesis in plasma, detoxification.

Blood on average for an hour passes through the liver in a volume of 1.5 liters, and per day 2000 liters.

Also, the liver is a temperature balance in the human body, which keeps the temperature within 37 ° C.

In an intrauterine child at the age of 8-10 the liver has the weight of half of the entire fetus.

Thousands of chemical reactions occur regularly in the liver. It is called a filter or a chemical plant, since the liver cleanses our body of toxins and toxins, and also produces substances necessary for life. From 18 to 20 hours the liver most actively removes harmful substances.

Without the liver, we would receive very strong poisonings, even from milk or water.

It is difficult to meet a person who has a healthy liver by the age of 35-40 due to stress, ecology, malnutrition, various medications.

If a person expresses a negative, then the liver suffers. If we carry this negative in ourselves, then its cells suffer even more. Therefore, many doctors assure that one must have self-control, do not keep evil, learn to forgive and control one's emotions.

Facts about the aorta

Факты об аорте Невероятные факты о человеческом теле. Внутренние органы.

The aorta is almost like a garden hose. If you take into account that the adult heart is almost the size of a fist, the size of the aorta is quite impressive.

In fact, the arteries should be large enough, because this is the main supplier of blood enriched with oxygen to the rest of the organs.

Human lungs

Легкие человека Невероятные факты о человеческом теле. Внутренние органы.

Our left lung is less than right. This nature has created in order to be where to fit in the heart. Both lungs are similar in shape to each other.

Through your lungs, 10,000 liters of air passes daily.

On average, an adult makes 23,000 breaths per day.

If you abuse alcohol, the proteins that protect the lung tissue function will be destroyed. This process is called "alcoholic lung".

A person living in the city for 60 years must cope with 0.1 g of metals, 200 g of harmful chemicals and 16 g of dust.

95% of people who died of lung cancer, smoked 40-20 cigarettes a day.

Substances that have an anti-cancer effect are called isothiocyanates. Using vegetables containing isothiocyanates (broccoli, Chinese cabbage) at least once a week you reduce the risk of lung cancer by more than 30%.

The number of people suffering from bronchopulmonary diseases, doubles every decade. Urban residents have a higher risk of getting these diseases than rural ones.

Human Vitality

Живучесть человека Невероятные факты о человеческом теле. Внутренние органы.

If a person takes away most of the internal organs, he will survive. The human body may seem fragile, but it will live even when removing the stomach, spleen, 75% of the liver, 80% of the intestine, one kidney, one lung and the genitals.

Interesting fact! The 25-year-old Phineas Gage was on earthwork in the US and an accident happened to him. When a dynamite checker exploded, a heavy metal rod 109 cm long and 3 cm in diameter flew out. He plunged into Phineas's cheek, knocking out the tooth, and then passed through the skull and brain to fly.

It's amazing that Gage did not die on the spot. Then he lost a tooth and an eye. Soon he completely recovered, retaining his mental faculties, speechlessness and complete control of the body.

Facts about the adrenal glands

Факты о надпочечниках Невероятные факты о человеческом теле. Внутренние органы.

Adrenal glands (paired endocrine glands) vary in size throughout our life. The adrenal glands, being above the kidneys, are responsible for the production of stress hormones (cortisol and adrenaline). On the seventh month of the fetus, these glands are about the same size as the kidneys.

At birth, the adrenal glands become smaller and will continue to do so throughout life. When a person reaches old age, the glands are so small that they can hardly be seen.

Both adrenals consist of a brain substance and a cortical layer.

They regulate the concentration of several substances in the blood and metabolic processes.

Adrenaline, which is secreted by the adrenal glands, signals the danger to the human body. This causes you to accelerate your breathing, increase the flow of blood and quickly beat the heart. Adrenaline is thrown into the blood in order to prepare for a danger or run away from it.
