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 arteries carry oxygenated blood with the exception of the pulmonary artery from the right side of the heart to the lungs, which does not. Yes.Most arterial blood is oxygenated. There are two exceptions to that rule. One is the pulmonary artery which carries deoxygenated blood. Veins do carry deoxygenated (oxygen-poor) blood into the heart.   Superior and inferior vena cava carry the oxygen-poor blood to the heart; blood enters into the righ â¦ t atrium.   Contraction of the atria forces the blood into the ventricles.
