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.
All three are types of blood vessels. Arteries carry freshly-oxygenated blood away from the heart and supply it to organs and other parts of the body that need oxygen. Veins carry oxygen-depleted blood back to the heart.Capillaries are tiny blood vessels that branch off from arteries and veins, and that most closely interact with tissue to supply oxygen to them (or carry oxygen-depleted blood away from them).Mark H Â· 9 years ago.eins carry oxygen-depleted blood back to the heart.
