Anonymous users2024-02-05A person pumps about 5 liters of blood per minute and about 300 liters of blood per hour at rest. Pumps about 7,200 liters of blood in 24 hours.
When a person's heart beats about 70 times per minute in a quiet state, pumping 70 milliliters of blood each time, it pumps about 5 liters of blood per minute, so it is estimated that the work done by a person's heart to pump blood in a lifetime is about equivalent to the work done by lifting a 30,000-kilogram object up to the summit of the Himalayas. The heart muscle that makes up the heart contracts and relaxes rhythmically, forming the heart's beat.
When the heart muscle contracts, it pushes blood into the arteries and throughout the body; When the heart muscle relaxes, blood flows back to the heart from a vein. Therefore, the beating of the heart drives the flow of blood and is the power organ of blood transportation.
When the heart is overloaded or the muscles are damaged, its pumping function is reduced, the output of blood cannot meet the needs of organs and tissues, and the blood in them cannot flow back to the heart smoothly, this state is called heart failure, referred to as "heart failure".
