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.
Veins carry blood back to the heart. They don t always bring deoxygenated blood because pulmonary vein makes the exception. It brings oxygen-rich blood from the lungs. They have thin wall and valves.
