Coronary arteries are a system of blood vessels that supply heart muscles with oxygen and nutrients to keep the heart functioning. It is so called because the system of arteries is in the shape of a corona.

If, for any reason, the coronary arteries become narrowed or blocked, blood flow to the heart will diminish and the supply of oxygen to the heart muscles will decrease or stop.  The patient will have chest pain and in the severe case a heart attack.
