The heart acts as a living pump. It pumps blood to all the different parts of the body. Red blood cells are carriers of oxygen as they have haemoglobin in them. Blood vessels are the pathways that help in transporting blood containing oxygen and other important substances throughout the body. Circulation is the process of movement of materials throughout the body.
