which supply the heart muscle (or myocardium) with oxygen, thus keeping it alive and perfectly functional.
Coronary artery disease, on the other hand, is, as the name suggests, a disease of the coronary arteries, a disease on which heart suffering depends.
This article will deal with analyzing the anatomy and physiology of coronary arteries, and dealing with coronary artery disease in detail.
