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.
Actually, arteries carry oxygen-rich blood to the body, whereas veins carry oxygen-poor blood back to the heart. The only exception to this rule is the Pulmonary Artery, which carries oxygen-poor blood to the lungs.It is called an artery because it carries blood from the heart instead of towards it.he blood in the pulmonary artery is oxygen-poor. yes all the arteries carry oxygenated blood except pulmonary artery which carry de â¦ oxigenated blood from the right ventricle of the heart towards the lungs.. I don't know what arties are, but arteries carry oxygen-rich blood while veins carry CO2 rich blood. Answered.
