What are the coronary arteries?

• Arteries are vessels that carry blood away from the heart. The coronary arteries are the first blood vessels that branch off from the ascending aorta.

Function:

• Carry oxygenated and nutrient filled blood to the heart muscle.

Branches:

• Right Coronary Artery - Supplies oxygenated blood to the walls of the ventricles and the right atrium.

• Left Main Coronary Artery - Directs oxygenated blood to the left anterior descending artery and the left circumflex.
  
  
  • Left Anterior Descending Artery - Supplies oxygenated blood to the walls of the ventricles and the left atrium (front region of the heart).
    
    
  • Left Circumflex Artery - Supplies oxygenated blood to the walls of the ventricles and the left atrium (back region of the heart).
