Left coronary artery
Left auricle is retracted to show the left coronary. It arises from the left coronary sinus and divides soon after into two almost equal branches. One descending between the two ventricles anteriorly is the left anterior descending. Curving around in the coronary /atrioventricular sulcus is the circumflex branch. These coronary arteries are the sole arterial supply to the heart muscle. What part does each supply?
