Which vessel carries oxygen-rich blood from the heart to the body?

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

Answer: (A)

Blood that has picked up oxygen is sent to the body through the aorta, the main artery of systemic circulation. After the left ventricle contracts, oxygen-rich blood enters the aorta and is distributed to tissues via a network of arteries. The other vessels serve different roles: the pulmonary artery carries blood from the heart to the lungs to release carbon dioxide and pick up oxygen (it carries deoxygenated blood), the vena cava brings deoxygenated blood back to the heart from the body, and the pulmonary veins return oxygenated blood from the lungs to the heart. Thus the aorta is the vessel that transports oxygen-rich blood from the heart to the rest of the body.
