The aorta serves to deliver what type of blood from which chamber to the body?

• A. Oxygenated blood from the left ventricle
• B. Deoxygenated blood from the right atrium
• C. Oxygenated blood from the right ventricle
• D. Deoxygenated blood from the left atrium

Answer: (A)

Systemic circulation carries oxygenated blood from the heart to the body. The aorta is the main artery that receives this blood from the left ventricle after it contracts and pushes blood through the aortic valve. This oxygen-rich blood then travels through the body's arteries to supply tissues, and after delivering oxygen, returns as deoxygenated blood to the heart via the venae cavae into the right atrium. The alternative descriptions mix up where the blood goes or its oxygen content: the right atrium holds deoxygenated blood returning from the body, not sending it to the body via the aorta; the right ventricle sends blood to the lungs for oxygenation, not to the body; the left atrium passes oxygenated blood to the left ventricle, not directly to the body.
