The coronary arteries originate as the right and left main coronary The coronary arteries branch off the aorta and wrap around the heart, and the branches of the main arteries bring blood deep into the heart muscle. There are two There are two main coronary arteries which branch to supply the entire heart. These are the left and right coronary arteries which arise from the left and right The coronary arteries deliver blood to the heart muscle, providing a continuous supply of oxygen and nutrients needed for it to stay healthy and function normally The coronary arteries arise from the coronary sinuses immediately distal ( superior) to the aortic valve and supply the myocardium of the heart with oxygenated May 13, 2016 The atherosclerotic coronary vasculature is not only the culprit but also a victim of myocardial ischemia/reperfusion injury.
