The human heart creates enough pressure to splash blood at a distance of 9 m. It is not surprising that you feel well the beat of your heart. This blood pump transports blood throughout the body quickly and efficiently, thanks to strong heartbeats.

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

A newborn baby has one cup of blood circulating. An adult's circulatory system holds 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 an adequate supply of oxygen.

At this point in your heart is 5% of the total amount of blood, 20% of the blood enters the brain and the central nervous system, 22% enters the kidneys.

That is, it is possible to expand all the 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 replaced with new ones. White blood cells (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 of the blood circulates through the body in the vessels. The other half are in spare “blood depots”. These "depot" include the liver, spleen and skin. Hypodermic vessels contain 10%, spleen 16% and liver up to 20% of the total amount of blood.

About 46% of the blood contained in the "blood depot". If the need to replenish blood happens, it is thrown from 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 blood loss. After the replenishment takes place, part of the blood is refilled in the skin, spleen and liver.

Recently, it has been found that susceptibility to various diseases depends on blood type. Doctors confirmed genetic studies.

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

People with the second blood group can suffer from rheumatic diseases, allergies, asthma, diabetes, heart disease.

People with the third blood group are more likely to suffer from pneumonia. They are prone to infections. Women often have purulent mastitis, sepsis after childbirth, joint disease and osteochondrosis.

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

It is not only predispositions associated with the blood group that are inherited, but also the diseases themselves. It may be intestinal infections, sore throats, pharyngitis or chronic tonsillitis.

The Japanese researched found that the first blood group even affects the person’s character.

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

In order for the blood to be saturated 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 metabolism, and you always get the necessary amount of oxygen.

Female heart

Женское сердце Невероятные факты о человеческом теле. Внутренние органы.

The female heart beats faster than the male. 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, this is not all. Male and female hearts may actually work quite differently, especially when injured from a heart attack and other diseases. The treatment that is suitable for the male heart does not always help the female.

The walls of the female heart in the left chamber prevail in the characteristics with the same male walls in elasticity and subtlety. The more elastic the walls in the heart chamber, the less likely hypertensive diseases.

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

In medical science, the causes of the diagnostic features of cardiac 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 have long been accustomed to believe that cardiovascular diseases are mainly manifested in men. Recently, however, statistics indicate that women suffer from such diseases in a more severe form. Fatal outcome in such cases in women is 55%, and in men 45%.

Liver function

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 intoxication. But the liver is one of the hardest-working and largest organs.

Here is a list of only a few of the main purposes of the liver: the production of bile, the decomposition of red blood cells, protein synthesis in plasma, detoxification.

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

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

In an intrauterine child, at 8–10 weeks, the liver has a weight of half of the entire fetus.

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

Without the liver, we would get very bad poisoning 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, and 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 you need to have composure, do not keep evil in yourself, learn to forgive and control your emotions.

Facts about the aorta

10,000 liters of air flow through your lungs daily.

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

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

A person living in a 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 anticancer effect are called isothiocyanates. Eating vegetables containing isothiocyanates (broccoli, Chinese cabbage) at least once a week reduces 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 such diseases than rural ones.

Human vitality

Живучесть человека Невероятные факты о человеческом теле. Внутренние органы.

If a person takes most of the internal organs, he will survive. The human body may seem fragile, but it will live even if the stomach, spleen, 75% of the liver, 80% of the intestines, one kidney, one lung and genitalia are removed.

Interesting fact! Phineas Gage, a 25-year-old worker, was excavating in the United States and had an accident. When the dynamite sting exploded, a heavy metal rod 109 cm long and 3 cm in diameter flew out. He plunged into Phineas' cheek, knocking out a tooth, and then passed to fly through the skull and brain.

Surprisingly, Gage did not die on the spot. Then he lost a tooth and an eye. Soon he fully recovered, retaining his mental abilities, speech and complete control over the body.

Adrenal gland facts

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

Adrenal glands (paired endocrine glands) vary in size throughout our lives. The adrenal glands, located above the kidneys, are responsible for the production of stress hormones (cortisol and adrenaline). In 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 adrenal glands are composed of medulla and 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 the breathing to speed up, the blood flow to increase and the heart to beat faster. Adrenaline is released into the bloodstream in order to prepare for danger or run away from it.
