Coronary circulation is the circulation of blood in the blood vessels of the myocardium. The vessels that deliver oxygen-‐rich blood to the myocardium are known as coronary arteries. The vessels that remove the deoxygenated blood from the heart muscle are known as cardiac veins. Anatomical organization The coronary circulation starts at the beginning of the aorta; here we find two arteries in the right and the left side! right and left coronary arteries. Both arteries have several superficial branches that lie on the surface of the heart (these are the ones with the bigger diameter), smaller arteries then penetrate from the surface into the cardiac muscle mass! subendocardial arteries.
