Incredible facts about the human body. Internal organs.
We do not remember the internal organs until they bother, although thanks to them we eat, breathe and walk.
Let's get acquainted with unusual facts that may amaze you.
The largest organ is the small intestine. It is four times longer than the average adult.
The normal human intestine contains about 1 kg of bacteria.
In the intestines of the Japanese are unique microbes that help to process the seaweed used in making sushi much better than people of other nationalities.
A person’s heart creates enough pressure to spill blood at a distance of 9 m. It is not surprising that you feel your heartbeat well. This blood pump carries blood throughout the body quickly and efficiently, thanks to strong heartbeats.
The heart begins to beat from the fourth week after conception, and does not stop until the death of a person.
In a newborn baby, one cup of blood circulates. The circulatory system in an adult 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 g, 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 that there is a sufficient supply of oxygen.
At the moment, 5% of the total amount of blood is in your heart, 20% of the blood goes to the brain and central nervous system, 22% goes to the kidneys.
The acidity of the stomach is so strong that it can dissolve the razor. However, you should not take this information too seriously and specifically swallow a razor or other metal objects.
The type of hydrochloric acid that was found in the stomach not only dissolves your dinner well, but is also able to dissolve many types of metals.
It is estimated that in the human body 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, to decompose all the blood vessels of one person in length around the Earth can be more than two times.
Blood cells are constantly dying 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.
Through the body, only half of the blood circulates in the vessels. The other half are in the spare blood depots. Such "depots" include the liver, spleen and skin. The subcutaneous vessels contain 10%, the spleen 16% and the liver up to 20% of the total amount of blood.
About 46% of the blood is in the “blood depot”. If there is a need for replenishment of blood, then 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 muscle work or blood loss. After replenishment takes place, part of the blood is again filled in the skin, spleen and liver.
Recently, it has been discovered that predisposition to various diseases depends on the blood group. Doctors have confirmed studies by geneticists.
People with the first blood group are predisposed to gastrointestinal diseases.
People with the second blood group can suffer from rheumatic diseases, allergies, asthma, diabetes, heart disease.
People with a third blood group are more likely than others to suffer from pneumonia. They are prone to developing infections. Women often have purulent mastitis, sepsis after childbirth, joint diseases and osteochondrosis.
People with the fourth blood type suffer from colds, flu, and other infections.
Not only the predispositions associated with the blood group, but also the diseases themselves are inherited. It can be intestinal infections, tonsillitis, pharyngitis or chronic tonsillitis.
Japanese researchers found that the first blood group even affects a person’s character.
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 due to strong digestive acids.
People who have an ulcer know how painful it can be without such a membrane in the stomach.
The area of a person’s lungs is equal to a tennis court.
In order for the blood to be saturated with oxygen, the lungs are made up of thousands of tiny branches of the bronchi. They, in turn, are filled with microscopic capillaries, in which oxygen and carbon dioxide.
The large area of the lungs facilitates the metabolism, and you always get the necessary amount of oxygen.
The female heart beats faster than the male. The reason for this is only that the mass of the female body is usually less than the mass of the male.
However, this is not all. Male and female hearts can actually work very differently, especially when injured by 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 characteristics with the same male walls in elasticity and subtlety. The more flexible the walls in the heart chamber, the less likely there is hypertension.
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 cardiological diseases in women are not yet clear. For example, it is not known why electrocardiographic examination in women is less reliable than in men.
Doctors have long been accustomed to believe that cardiovascular disease is mainly manifested in men. However, recently 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%.
Scientists have over 500 different liver functions. We are accustomed to remembering the liver only after intoxication. But the liver is one of the most hardworking and largest organs.
Here is a list of just a few basic purposes of the liver: production of bile, decomposition of red blood cells, plasma protein synthesis, detoxification.
Blood on average per 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 8-10 weeks, the liver has a weight of half the entire fetus.
Thousands of chemical reactions occur regularly in the liver. It is called a filter or chemical plant, as the liver cleanses our body of toxins and toxins, and also produces the substances necessary for life. From 18 to 20 hours, the liver most actively removes harmful substances.
Without the liver, we would get very severe 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, the environment, poor nutrition, and various medications.
If a person expresses a negative, then the liver suffers. If we carry this negative within us, then its cells suffer even more. Therefore, many doctors assure that you need to have self-control, not to keep evil in yourself, to learn to forgive and control your emotions.
Facts About Aorta
Aorta diameter is almost like a garden hose. Given that an adult heart is almost the size of a fist, the size of the aorta is very impressive.
In fact, the arteries should be large enough, because it is the main supplier of blood enriched with oxygen to other organs.
Our left lung is smaller than the right. This nature created in order to have where to fit the heart. Both lungs are similar in shape to each other.
10,000 liters of air passes through your lungs daily.
On average, an adult takes 23,000 breaths a day.
If you abuse alcohol, then 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 needs to 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 per day.
Substances that have anti-cancer effects are called isothiocyanates. Eating vegetables containing isothiocyanates (broccoli, Chinese cabbage) at least once a week reduces your 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 contracting such diseases than rural ones.
If a person takes away most of the internal organs, then 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 genitals are removed.
Interesting fact! The 25-year-old worker Phineas Gage was at earthworks in the United States and had an accident with him. When the dynamite block exploded, a heavy metal rod flew out 109 cm long and 3 cm in diameter. It stuck into Phineas' cheek, knocking out a tooth, and then went out through the skull and brain.
Surprisingly, Gage did not die on the spot. Then he lost his tooth and eye. Soon, he fully recovered, retaining his mental abilities, speechlessness and complete control over the body.
The adrenal glands (paired endocrine glands) change in size throughout our lives. The adrenal glands, located above the kidneys, are responsible for the production of stress hormones (cortisol and adrenaline). At the seventh month in 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 the medulla and the cortex.
They regulate the concentration of several substances in the blood and metabolic processes.
Adrenaline, which is secreted by the adrenal glands, signals a danger to the human body. This makes you accelerate breathing, increase blood flow and beat your heart faster. Adrenaline is released into the blood in order to prepare for or run away from danger.
