There are three major types of blood vessels: the arteries, which carry the blood away from the heart; the capillaries, which enable the actual exchange of water and chemicals between the blood and the tissues; and the veins, which carry blood from the capillaries back toward the heart.
Best Answer: Arteries are blood vessels that carry oxygenated blood away from the heart. Exceptions to this include the pulmonary and umbilical arteries. Capillaries are the smallest of a body's blood vessels and are part of the microcirculation. They are only 1 cell thick.rteries are muscular blood vessels that carry oxygenated blood away from the heart (except the pulmonary and umbilical arteries). Arteries carry oxygen-rich blood at high pressure, so they are tough on the outside and smooth on the inside.
