There are three kinds of blood vessels: arteries, veins, and capillaries. Each of these plays a very specific role in the circulation process. Arteries carry oxygenated blood away from the heart. Theyâre tough on the outside but they contain a smooth interior layer of epithelial cells that allows blood to flow easily.
The heart and blood vessels (arteries, capillaries, and veins) are called the cardiovascular system. The cardiovascular system carries blood throughout the body. The heart pumps blood through blood vessels called arteries and then through smaller blood vessels called capillaries to each organ and tissue in the body.
