Verified step by step guidance

Understand the function of each vessel mentioned: Pulmonary veins, Coronary arteries, Pulmonary arteries, and Aorta.

Recall that the pulmonary arteries are responsible for carrying blood from the heart to the lungs. This blood is oxygen-poor because it has just returned from the body and needs to be re-oxygenated in the lungs.

Recognize that pulmonary veins carry oxygen-rich blood from the lungs back to the heart, which is the opposite of what pulmonary arteries do.

Identify that coronary arteries supply oxygen-rich blood to the heart muscle itself, and the aorta is the main artery that carries oxygen-rich blood from the heart to the rest of the body.

Conclude that among the options given, the pulmonary arteries are the vessels that carry oxygen-poor blood, as they transport deoxygenated blood to the lungs for oxygenation.
