The function of the coronary arteries is to transport oxygenated blood to the heart--------not to other parts of the body !!
The vessels that deliver oxygen-rich blood to the myocardium are known as
coronary arteries
.
The coronary arteries that run on the surface of the heart are called epicardial coronary arteries. These arteries, when healthy, are capable of autoregulation to maintain coronary blood flow at levels appropriate to the needs of the
heart muscle.
The coronary arteries are classified as "end circulation", since they represent the only source of blood supply to the myocardium.
