Coronary Artery

The Coronary Artery (pronunciation: kuh-ROH-nuh-ree AHR-tuh-ree) is a major blood vessel that supplies the heart with blood, oxygen, and nutrients.

Etymology

The term "Coronary" is derived from the Latin word "corona" meaning crown, and "artery" from the Greek word "arteria" meaning windpipe. This is due to the way the coronary arteries encircle the heart in a crown-like fashion.

Function

The coronary arteries are responsible for delivering oxygen-rich blood to the myocardium, which is the muscular layer of the heart wall. There are two main coronary arteries, the right coronary artery (RCA) and the left coronary artery (LCA). These arteries branch off into smaller arteries to supply blood to all parts of the heart.
