Question

The coronary circulatory system arises from which vessel and drains into which structure?
Options
A Pulmonary artery — drains into the left atrium
B Aorta — drains through the coronary sinus into the right atrium
Correct Answer
C Vena cava — drains into the right ventricle
D Pulmonary vein — drains into the left ventricle
Correct Answer

Option B is the correct answer.

Detailed Explanation

The coronary circulatory system arises from the aorta (just beyond the aortic valve) and drains through the coronary sinus into the right atrium. This pathway ensures the heart muscle receives oxygenated blood and deoxygenated blood returns appropriately.

Hint

These vessels branch off the main artery leaving the heart and return blood to the receiving chamber.
