PATHOLOGY

Detailed explanation-1: -It pumps the blood to your lungs to collect a fresh supply of oxygen. The left side of your heart pumps the re-oxygenated blood round your body again.

Detailed explanation-2: -What Does the Heart Do? The heart is a pump, usually beating about 60 to 100 times per minute. With each heartbeat, the heart sends blood throughout our bodies, carrying oxygen to every cell. After delivering the oxygen, the blood returns to the heart.

Detailed explanation-3: -There are two phases to your heart’s pumping cycle: systole-this is when your heart contracts, pushing blood out of the chambers. diastole-this is the period between contractions when the muscle of your heart (myocardium) relaxes and the chambers fill with blood.
