Answer:
The correct answer will be option B-left atrium.
Explanation:
The coronary circulation is the circulation of blood and nutrients to the myocardium of the heart on both sides.
The coronary system consists of coronary arteries and coronary sinus(vein) in which coronary arteries arise from the main artery of the circulatory system called aorta. This aorta arises from the left atrium of the heart which supplies oxygenated blood. These coronary arteries divide into left and right arteries which supply oxygenated blood to the heart.
