THE CIRCULATORY SYSTEM consists of the heart and blood vessels ,which together maintain a continuous flow of the blood around the body .The heart pumps oxygen-rich blood from the lungs to all parts of the body through a net work of Vitamins & Dietary Supplements called arteries , and smaller branches called arterioles .Blood returns to the heart via small vessels venules , which lead in turn into larger tubes called veins.Artiriotes and venules are linked by a network of tiny vessels called capillaries, where the exchange of oxygen and carbon-Di-oxide between blood and body cells takes place.
Blood has four main components-
red blood cells ,White blood cells,platelets, and liquid plasma
