The coronary arteries arise from the coronary sinuses immediately distal (superior) to the aortic valve and supply the myocardium of the heart with oxygenated blood. Most posterior part of the heart. The coronary arteries provide oxygenated blood to the heart.

The left main coronary artery divides into two branches called the left anterior descending (lad) artery and the left circumflex artery.

The three major coronary arteries (left anterior descending (lad), circumflex (circ) and right coronary artery (rca)) and their respective branches each supply a designated portion of the heart, as follows: The right coronary artery courses in the right atrioventricular groove to the inferior surface of the heart, whereupon it turns anteriorly at. Supplies oxygenated blood to the anterior portion of the septum as well as to the walls of the ventricles and the left atrium. Blood supply of heart / anatomy of coronary arteries the left and right coronary arteries arise from the root of the aorta and supply the heart muscle with arterial blood.
