The heart’s role for the entire body is not only limited to pumping blood. It also needs its own blood supply to be able to perform its several functions. The process of the heart managing its own blood supply is known as coronary circulation. The walls situated in the heart have systemic blood vessels. These exist to meet the needs of the heart for blood supply. Oxygenated blood is brought to the myocardium via the left and right coronary arteries. They are also responsible for bringing the myocardium the needed blood supply by branching off. Atrioventricular sulcus, otherwise known as the depression between the right and left ventricles and the atrias, carry the coronary arteries which enclose or surround the diameter of the heart.
