Which organ pumps blood throughout the human body?
Heart
Heart is the muscular four-chambered organ which pumps blood throughout the body. It is also called as the central pumping organ of the body. Blood vessels and capillaries are the ways by which blood is supplied to all body parts. Lungs are the sites for gaseous exchange where blood is oxygenated and carbon dioxide is removed from it. Kidneys filter the blood to remove nitrogenous waste material.
