The cardiovascular system is made up of the heart, arteries, veins, capillaries, blood vessels and cells. All of these elements function together to create the system that transports oxygen and other nutrients to our organs and then removes waste products. As the heart pumps the blood cells are transported through the body via the arteries and the veins. The heart receives deoxygenated blood that has travelled through the body and then sends blood through the pulmonary artery to the lungs where it is oxygenated before being passed around the body.

The blood that passes around our bodies is made up of red blood cells, white blood cells, platelets and plasma. Each of these plays an important role. Red blood cells carry oxygen to our organs, white blood cells help us to fight infection, platelets help in clotting and plasma helps to deliver nutrients and remove waste products.
