Question

Why quantity of blood entering the heart determines the quantity of blood heart gives out?

Answer 1

Heart:

1. The heart is a muscular organ that pumps blood to the entire body.
2. It has four chambers divided into left and right sides.
3. The heart pumps oxygenated blood to the body and deoxygenated blood to the lungs.
4. The quality of blood entering the heart determines the quantity of blood the heart gives out because the heart pumps the same quantity of blood out to the lungs or the body as much it receives from the lungs or veinous system.
