MEDICAL PHYSIOLOGY

Detailed explanation-1: -The coronary arteries also supply the myocardium with oxygen to allow for the contraction of the heart and thus causing circulation of the blood throughout the body. Two main coronary arteries originate from the base of the aorta as it exits the left ventricle: the left and right coronary arteries.

Detailed explanation-2: -Myocardial oxygen demand is the amount of oxygen that the heart requires to maintain optimal function, and myocardial oxygen supply is the amount of oxygen provided to the heart by the blood which is controlled by the coronary arteries.
