The heart is an organ that beats continuously to act as a pump for the transport of blood, which carries other substances with it. The heart pumps the deoxygenated blood to the lungs for oxygenation and receives oxygenated blood from the lungs. It pumps the oxygenated blood to different parts of the body. There is double circulation in a human heart that creates lub- dub sound.
