What is the size of the heart? If you are a child, your heart will be the size of a fist, for an adult, your heart will be as big as 2 fists of that person. At 4 weeks pregnant, the heart begins to beat for the first time and stops beating only when the person dies. When the body is in a state of rest without mental and physical exercise, it takes only 6 seconds for blood to flow from the heart to the lungs and back, and about 8 seconds for blood to return from the heart to the brain. A healthy heart pumps about 2,000 liters of blood every day to the entire length of the vascular system in the body, about 96,500 km. The energy produced by the heart a day is enough to drive a truck about 32 km. The pressure generated by the heart in one heartbeat is enough to spray blood about 9 meters away. The average adult's heart beats 72 times a minute, 100,000 times a day, 3,600,000 times a year, and over a lifetime the heart beats about two trillion times. A woman's heart beats an average of 78 times a minute and a man's 70 times a minute. Every 10 seconds the heart pumps more than 1 liter of blood or about 5 liters of blood per minute. In pregnant women, in the last trimester of pregnancy, the heart pumps from 7-9 liters of blood per minute. And even the heart can pump at most 20-35 liters of blood per minute. The heart can continue to beat even when it is separated from the body because it has its own electrical impulses. The left lung is smaller than the right lung to make room for the heart. People who are in love in the happy phase can beat at the same rate after they look into each other's eyes for 3 minutes. The heart pumps blood to almost all parts of the body. In the body there are about 75 trillion cells that receive blood from the heart, with the exception of the cornea which does not receive a blood supply.
