The aorta is the main artery that does what?

• A. Carries oxygenated blood from the heart to the body
• B. Carries deoxygenated blood to the lungs
• C. Returns blood to the heart
• D. Produces blood cells

Answer: (A)

The aorta’s role is to distribute oxygenated blood from the heart to the rest of the body as the main artery of systemic circulation. It carries blood that has just been pumped from the left ventricle, delivering oxygen to tissues as it travels through its branches. After tissues use the oxygen, blood returns to the heart through the venous system, not through the aorta. Blood to the lungs for oxygenation travels via the pulmonary arteries from the right ventricle, which is a different circuit. Producing blood cells occurs in bone marrow, not in arteries. So the statement describing the aorta as carrying oxygenated blood from the heart to the body is the correct one.
