Heart is made of a special muscle called myocardium. It is enclosed in a double layered membranous called “pericardium”. It lies between the lungs. It contains four chamber, large arteries and veins. These four parts or chambers are named as atrium and ventricles. A muscle wall divides heart into two different cavities. The right cavity pumps blood throughout the boy whereas the left cavity pumps blood throughout the human body. The two upper chambers of the heart are called atrium while the bottom chambers are called ventricles. Chamber of right side receives blood from the body and the left side receives oxygenated blood from the lungs. This left side pumps the blood to the rest of the body. A healthy heart beats near about 100000 times a day. It pumps about 2000 gallons of blood. Our heart pumps nearly five quarts of blood through our body in every minutes. A heart beats about 3 billion times during a seventy years life. Any accidental damage to the heart can reduce its pumping power.
