The heart is also known as the blood-pump of the body. It pumps blood through the circulatory system to all parts of the body. The blood carries food and oxygen to the cells and carries away carbon dioxide and waste materials. -The right hand side of the heart receives de-oxygenated blood from the body tissues, and pumps it to the lungs. The left-hand side of the heart receives oxygenated blood from the lungs and pumps it into the body, so that the oxygen can be delivered to cells..............
