Veins take blood to the heart, while arteries take blood away from the heart. Also, veins have valves that don't allow backflow because their wall contains almost no smooth muscle to pump the blood - they cannot constrict and dilate on their own. Veins rely on the body's muscular movement to move the blood contained in them. Arteries, however, can constrict or dilate to diver blood flow to different parts of the body and to keep blood pressure relatively constant. They have a large smooth muscle component in their walls.
