The vascular system or the circulatory system is made up of the vessels that carry blood and lymph through the body. The vascular system is an organ system with a network of vessels and organs that permits blood to flow and circulate to transport necessary body substances to and from the cells. There are three varieties of blood vessels, Arteries, Capillaries and Veins. Arteries carry oxygenated blood away from the heart, Veins carry blood from the body back into the heart. Capillaries are the tiny blood vessels between arteries and veins that distribute oxygen-rich blood to the body.
