Detailed explanation-1: -Overview. Your heart is divided into two separate pumping systems, the right side and the left side. The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide.

Detailed explanation-2: -The heart is an organ which 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 lungs. It pumps the oxygenated blood to different parts of the body.

Detailed explanation-3: -It’s the muscle at the centre of your circulation system, pumping blood around your body as your heart beats. This blood sends oxygen and nutrients to all parts of your body, and carries away unwanted carbon dioxide and waste products.

Detailed explanation-4: -The heart is a muscular organ that pumps blood continuously throughout the body. It is comprised of four chambers-the right and left atrium and the right and left ventricle. The four chambers of the heart work together by alternately contracting and relaxing to pump blood throughout the heart.
