The heart is responsible for the functioning of all organs. Stopping the "motor" becomes the reason for the cessation of blood circulation, which means that it leads to the death of all organs. Most people know this, but there are many other amazing facts about the heart. Some of them are desirable for everyone to know, as this will help to take timely measures that contribute to the smooth operation of the most important organ in the human body.

5. In a newborn, the total amount of blood circulating in the body is 140-15 ml per kilogram of body weight, in an adult this ratio is 50-70 ml per kilogram of body weight;
6. The force of blood pressure is such that when a large arterial vessel is injured, it can rise up to 10 meters;
7. With right-sided localization of the heart, one person is born in 10 thousand;
8. Normally, the heart rate of an adult is from 60 to 85 beats per minute, while in a newborn, this figure can reach 150;
9. The human heart is four-chambered, in a cockroach there are 12-13 such chambers and each of them works from a separate muscle group. This means that if one of the chambers fails, the cockroach will live without any problems;

13. According to the latest data, the working capacity of a healthy heart can last for at least 150 years;
14. The heart is divided into two parts, the left one is stronger and larger, as it is responsible for blood circulation throughout the body. In the right half of the organ, blood moves in a small circle, that is, from the lungs and back;
15. The heart muscle, unlike other organs, is capable of producing its own electrical impulses. This allows the heart to beat outside the human body, provided there is a sufficient amount of oxygen;
16. Every day the heart beats more than 100 thousand times, and in a lifetime up to 2.5 billion times;
17. The energy generated by the heart for several decades is enough to ensure the ascent of loaded trains to the highest mountains of the earth;
18. There are more than 75 trillion cells in the human body, and all of them are provided with nutrition and oxygen due to the blood supply from the heart. The exception, according to the latest scientific data, is the cornea, its tissues are fed by external oxygen;
19. With an average life span, the heart carries a volume of blood that is equal to the amount of water that can pour out of the tap in 45 years with a continuous flow;
20. The blue whale is the owner of the most gigantic heart, the weight of an adult's organ reaches almost 700 kilograms. However, a whale's heart beats only 9 times per minute;
21. The heart muscle performs the largest amount of work in comparison with other muscles in the body;
22. Primary heart tissue cancer is extremely rare. This is due to the rapid course of metabolic reactions in the myocardium and the unique structure of muscle fibers;
23. Heart transplant was successfully performed for the first time in 1967. The patient was operated on by Christian Barnard, a South African surgeon;
24. Heart disease is less common in educated people;
25. The largest number of patients with heart attacks go to the hospital on Monday, New Years and especially hot summer days;
26. Want to know less about heart pathologies - laugh more and more often. Positive emotions contribute to the expansion of the vascular lumen, due to which the myocardium receives more oxygen;
27. "Broken heart" is a phrase that is often found in literature. However, with strong emotional experiences, the body begins to intensively produce special hormones that can cause temporary shock and symptoms resembling a heart attack;
28. Stitching pains are not characteristic of heart disease. Their appearance is mostly associated with pathologies of the musculoskeletal system;
29. In terms of structure and principles of work, the human heart is almost completely identical with a similar organ in a pig;

37. Men are least likely to have a heart attack if their ring finger is much longer than the others;
38. The risk group for developing heart disease includes people with problem teeth and gum disease. Their risk of having a heart attack is about half that of those who monitor their oral health;
39. The electrical activity of the heart is greatly reduced by the influence of cocaine. The drug often becomes the main cause of strokes and heart attacks in practically healthy young people;
40. Inappropriate nutrition, bad habits, physical inactivity lead to an increase in the volume of the heart itself and to an increase in the thickness of its walls. As a result, it disrupts blood circulation and leads to arrhythmias, shortness of breath, heart pain, increased blood pressure;
41. A child who has experienced psychological trauma in childhood is more susceptible to cardiovascular pathologies in adulthood;
42. Hypertrophic cardiomyopathy is a diagnosis typical for professional athletes. Often causes death in young people;
43. Embryonic hearts and blood arteries are already 3D printed. It is possible that this technology will help to cope with fatal diseases;
44. Obesity is one of the causes of deterioration in heart function, both in adults and in children;
45. With congenital heart defects, cardiac surgeons perform operations without waiting for the baby to be born, that is, in the womb. This treatment minimizes the risk of death after birth;

51. During choral singing, the heart rate of all participants is synchronized, and the heartbeat is harnessed;
52. At rest, the volume of circulating blood per minute is 4 to 5 liters. But when performing hard physical work, the heart of an adult can pump from 20-30 liters, and for some athletes this figure reaches 40 liters;
