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.
