Which Vessel Supplies the Systemic Circuit with Oxygenated Blood

Question

Which vessel supplies the systemic circuit with oxygenated blood?
A)coronary sinus
B)superior vena cava
C)pulmonary trunk
D)aorta

Accepted Answer

The aorta is the largest artery in the body and delivers oxygen-rich blood to the systemic circuit, which includes all the organs and tissues of the body except for the lungs. The coronary sinus drains deoxygenated blood from the heart itself, the superior vena cava brings deoxygenated blood from the upper body to the right atrium, and the pulmonary trunk carries deoxygenated blood from the right ventricle to the lungs. Therefore, the correct option is (D) aorta as it's the only one supplying oxygenated blood to the systemic circuit.
