Because of the size (narrow) of the coronary arteries and their function in serving the heart itself, atherosclerosis can be deadly in these arteries.

Atherosclerosis is the blockage of an artery by the buildup of fatty plaques. The heart muscle will die without a steady supply of blood.

They diverge into capillaries where the heart muscle is supplied with oxygen before converging again into the coronary veins to take the deoxygenated blood back to the right atrium where the blood will be re-oxygenated through the pulmonary circuit. The coronary arteries branch from the aorta and surround the outer surface of the heart like a crown. The heart has its own blood vessels that supply the heart muscle with blood. The outer layer of cells is called the epicardium, of which the second layer is a membranous layered structure called the pericardium that surrounds and protects the heart it allows enough room for vigorous pumping but also keeps the heart in place to reduce friction between the heart and other structures. The myocardium consists of the heart muscle cells that make up the middle layer and the bulk of the heart wall. The inner wall of the heart has a lining called the endocardium.
