Which vein accompanies the anterior interventricular artery and drains into the coronary sinus?

• A. Left Pulmonary Artery
• B. Left Common Carotid Artery
• C. Anterior Interventricular Artery
• D. Great Cardiac Vein

Answer: (D)

The main concept is how the heart’s veins run with its arteries and drain into the coronary sinus. The vein that follows the anterior interventricular artery in the anterior interventricular sulcus collects blood from the regions supplied by the left coronary artery, particularly the anterior wall of the left ventricle. This great cardiac vein then drains into the coronary sinus, which channels blood into the right atrium. The other options aren’t veins in this pathway: the left pulmonary artery is an artery, the left common carotid artery is a neck artery, and the anterior interventricular artery is an artery as well. So the vein that matches this description is the great cardiac vein.
