Definition: Every muscle needs a blood supply, including the heart - and the coronary arteries are responsible for this. The coronary arteries are blood vessels that branch off the aorta -- the biggest artery in the body -- and supply blood to the heart muscle.
Coronary arteries are responsible for directly supplying the heart muscle with fresh blood and nutrients it needs to perform correctly.
Also Known As: Heart Vessels
Examples: Untreated coronary artery disease can lead to a heart attack.
