Which large vessel carries oxygenated blood away from the heart to the body?

Which large vessel carries oxygenated blood away from the heart to the body?

• A. Pulmonary artery
• B. Superior vena cava
• C. Aorta
• D. Inferior vena cava

Answer: (C)

Think about how blood moves through the body after it leaves the heart. The aorta is the main highway for oxygen-rich blood that is pumped out of the left ventricle and sent to all tissues in the body. It is this vessel that carries oxygenated blood away from the heart into systemic circulation, making it the best answer for the question. In contrast, the pulmonary artery carries blood to the lungs to pick up oxygen, but the blood is not yet oxygenated when it leaves the heart. The superior and inferior vena cavae bring deoxygenated blood back to the heart, not away from it. So they don’t fit the description of carrying oxygenated blood away to the body.
