Blood enters the coronary arteries just above the aortic semilunar valve. After systole (a ventricular contraction), the valve closes. The closing valve causes blood to back flow against the valve. At this time, the backward flow of blood enters into the coronary arteries.

Coronary circulation is the circulation of blood in the blood vessels of the heart muscle (the myocardium). The vessels that deliver oxygen-rich blood to the myocardium are known as coronary arteries. The vessels that remove the deoxygenated blood from the heart muscle are known as coronary veins.
