Answer: C

Explanation:

The pulmonary artery is the only artery to carry deoxygenated blood to the lungs for gas exchange. The pulmonary vein is the only vein to carry oxygenated blood back to the heart. Typically the arteries carry oxygen rich blood away from the heart to the systemic circulation. Veins typically carry deoxygenated blood back to the heart. The aorta is the main artery exiting the left ventricle to the body and the vena cava’s return blood back to the right side of the heart.
