Where are the coronary arteries located in?

The coronary arteries are located on the surface of the heart, branching off from the base of the aorta, just above the aortic valve. They encircle the heart muscle, supplying oxygen-rich blood to the myocardium. The two main coronary arteries are the left coronary artery, which further divides into the left anterior descending and circumflex arteries, and the right coronary artery. These arteries play a crucial role in maintaining the heart's health and function.
