Question

Describe the pumping cycle of the heart ?​

Answer 1

Answer:

Like a pump, the heart works in two phases: systole and diastole. At systole the right ventricle contracts to eject the venous blood into the lungs so that they are oxygenated, and in the left ventricle contraction ejects oxygenated blood into the entire systemic circulation.

Answer 2

Explanation:

The cardiac cycle is the performance of the human heart from the beginning of one heartbeat to the beginning of the next. It consists of two periods: one during which the heart muscle relaxes and refills with blood, called diastole, following a period of robust contraction and pumping of blood, dubbed systole.
