Veins have much thinner walls, because the blood they carry is under low pressure. VEINS have valves that aid the return of blood to the heart and prevent blood from going backwards. ARTERIES do not have valves, except for the semi-lunar valves of the pulmonary artery and the aorta. ARTERIES have relatively narrow lumens, VEINS have relatively wide lumens.
This is often a trick question, because a vein can carry oxygenated blood, and an artery can carry de-oxygenated blood in specific situations. **In general**, veins carry de-oxygenated blood towards the heart, and arteries carry blood rich in oxygen away from the heart.he pulmonary vein also carries oxygenated blood (from the lung back to the heart). The difference between an artery and a vein is that arteries carry blood away from the hear and veins carry blood to the heart. blankstar Â· 7 years ago. Thumbs up. 2. Thumbs down. 0. Comment.
