Pulmonary artery carries

• A. Vein carrying oxygenated blood from the heart to the body
• B. Artery carrying oxygen-poor blood from the heart to the lungs
• C. Vein returning blood from the lungs to the heart
• D. Artery carrying oxygenated blood from the lungs to the heart

Answer: (B)

Pulmonary circulation moves blood between the heart and the lungs. The vessel leaving the right ventricle is the pulmonary artery, and it carries blood that is low in oxygen from the heart to the lungs for gas exchange. After the blood picks up oxygen in the lungs, it returns to the heart through the pulmonary veins.

So this vessel is an artery and its job is to deliver oxygen-poor blood to the lungs. The other descriptions mix up vessel type, direction, or where the blood is routed: veins carry blood toward the heart (and the pulmonary veins carry oxygenated blood back to the heart), and arteries normally carry blood away from the heart (in systemic circulation) but in the pulmonary circuit the artery carries deoxygenated blood to the lungs.
