Which vessel carries deoxygenated blood from the heart to the lungs?

• A. Aorta
• B. Pulmonary Veins
• C. Pulmonary Artery
• D. Vena Cava

Answer: (C)

The main idea is that deoxygenated blood is sent from the heart to the lungs for gas exchange via the pulmonary artery. The right ventricle pushes this blood into the pulmonary artery, which carries it to the lungs. In the lungs, blood releases carbon dioxide and picks up oxygen, then the oxygenated blood returns to the heart through the pulmonary veins into the left atrium, moves to the left ventricle, and is pumped out to the body via the aorta. The vessel that carries deoxygenated blood to the lungs is the pulmonary artery. The aorta delivers oxygen-rich blood to the body, the vena cava brings deoxygenated blood back to the heart from the body, and the pulmonary veins carry oxygenated blood from the lungs back to the heart.
