How many pumps can a heart pump?

Answer 1

The heart pumps blood.

Answer 2

Because the blood has to be able to pass through the tiny capillaries in the lungs during gas exchange (the capillaries create a large service area that makes gas exchange more effecient), so the pressure has to be lower. If there was only one pump, the flow of blood to the rest of the body would be too slow and blood wouldn't reach are muscles quick enough.

So there are two pumps. The right venticle pumps blood a short distance to the lungs. The left ventricle is bigger as it must exert more pressure in order to pump the blood that is returned from the lungs to the rest of the body.

Answer 3

On an average, the heart of an adult beats about 72 times a minute and that of a child beats between 90 and 120 times a minute. Hence, in a day (that is, 1, 440 minutes), on an average, the adult heart beats 103, 680 times and a child's hearts beats between 129, 600 and 172, 800 times.

If you are referring to how many times the heart can beat in a lifetime, if we take the average person surviving the average age of a human life-span (approximately 80 years), then the average person's heat will be a staggering three billion times. This does not account for those suffering from rapid heart beat or other heart conditions and is a rough estimate.

Answer 4

There are two sides to the heart, separated by the Septum. On one side is the left atrium and left vesicle, and on the other side is the right atrium and right vesicle. Both are connected to the Aorta. It is considered to be two pumps because one side houses oxygenated blood and one houses de-oxygenated blood. De-oxygenated blood is pumped out of one side of the hear and is filtered through the lungs where it becomes oxygenated, and is then pumped into the other side of the heart which houses oxygenated blood. The oxygenated blood is then pumped through the arteries and circulated throughout the body. It has to do this in order to provide you cells with oxygen. When the blood is out of oxygen, it is pumped back into the de-oxygenated side of the heart and the process begins again. Therefore, your blood is always circulating in order to deliver oxygen, as well as other needed substances to the cells.

Answer 5

The human heart has 2 pumps. The right side of the heart pumps to/from the lungs (pulmonary circuit) and the left side of the heart pumps to/from the rest of the body (the systemic circuit).

Answer 6

it have many, but it has over 20 blood vessels so the heart can live. sorry that's what my teacher told me.

Answer 7

It both pumps blood to the lungs, through the pulmonary artery, as well as to the rest of the body, through the aorta.
