Question

how heart is work explain

Answer 1

The myocardium does the main pumping work: It relaxes to fill with blood and then squeezes (contracts) to pump the blood. "Contractility" describes how well the heart muscle squeezes. ... For this reason, yourheart pumps oxygen-rich blood to its own muscle through your coronary arteries.

Answer 2

Your heart is divided into two pumps, which work together. Blood coming back from the organs and tissues of your body enters the right side of your heart, which then pumps it to your lungs. Your lungs remove waste carbon dioxide from the blood and recharge it with oxygen.   OR, WE CAN SAY THAT, Blood carries oxygen and other important nutrients that all body organs need to stay healthy and to work properly. Your heart is a muscle, and its job is to pump blood throughout your circulatory system.  PLEASE MARK THIS ANSWER AS BRAINLIEST.....☺ KEEP ASKING........
