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.
Arteries carry oxygenated blood (with the exception of the pulmonary artery and umbilical artery). Veins carry deoxygenated blood (with the exception of pulmonary veins and umbilical vein).eins can be classified as pulmonary veins and systemic veins. The pulmonary veins are a set of veins that deliver oxygenated blood from the lungs to the heart and the Systemic veins drain the tissues of the body and deliver deoxygenated blood to the heart.
