Which vessel leaves the left ventricle to supply the body?

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

Answer: (D)

From the left ventricle, blood is pumped into the aorta, the main artery that sends oxygen-rich blood out to every part of the body. The left ventricle pushes blood through the aortic valve into the aorta with enough pressure to reach all tissues via the systemic circulation. The other vessels have different roles: the pulmonary artery carries blood from the right ventricle to the lungs, the pulmonary veins return oxygenated blood from the lungs to the left atrium, and the vena cava brings deoxygenated blood back to the right atrium from the body. So the vessel leaving the left ventricle to supply the body is the aorta.
