Coronary Arteries

• The heart is a muscle and, like the rest of the body, needs blood, oxygen and nutrients to survive.
• The heart muscle gets its blood supply from small blood vessels known as the coronary arteries. These arteries lie on the outside surface of the heart.
• There are 3 major branches of the coronary arteries:
  • Right Coronary Artery (RCA)
  • Left Anterior Descending (LAD)
  • Circumflex (Circ)
• Each of these major branches has many additional branches which supply all parts of the heart muscle with oxygen-rich blood.
