How much blood does the human heart pump in a day

The heart pumps 70 milliliters of blood each time, about 5 liters of blood per minute, and 7,200 liters of blood in 24 hours.

The role of the heart is to promote the flow of blood to the organs and tissues to provide adequate blood flow to supply oxygen and a variety of nutrients (such as water, inorganic salts, glucose, proteins, a variety of water-soluble vitamins, etc.), and take away metabolism of the end-products (such as carbon dioxide, urea and uric acid, etc.), so that the cells to maintain a normal metabolism and function.

A variety of endocrine hormones and some other humoral factors in the body, but also through the blood circulation to transport them to the target cells, the realization of the body's fluid regulation, to maintain the relative constancy of the body's internal environment.

Expanded

The adult heart weighs about 300 grams, and its role is huge, for example, a person in a quiet state, the heart beats about 70 times a minute, and each time you pump 70 milliliters of blood, it is about 5 liters of blood pumped per minute, so that a person's heart pumping the blood of a lifetime to do the work of the heart is equivalent to the 30,000-kilogram object upward to the Himalayas, and then the blood pumping work of the heart is the equivalent of the blood pumping work. Objects lifted up to the top of the Himalayas made by the work.

The myocardium that makes up the heart rhythmically contracts and diastoles to form the heart's beat. When the heart muscle contracts, it pushes blood into the arteries to flow throughout the body; when it diastoles, blood flows back to the heart from the veins. Therefore, the heart's beat pushes the flow of blood and is the power organ of blood transportation.
