Detailed explanation-1: -The coronary arteries arise from the aortic sinuses. The initial portion of the aortic root, which houses the leaflets of the aortic valve, is occupied by the aortic sinuses, also called the sinuses of Valsalva.
Detailed explanation-2: -There are two primary coronary arteries, the right coronary artery (RCA) and the left main coronary artery (LMCA). Both of these originate from the root of the aorta. The RCA emerges from the anterior ascending aorta and supplies blood primarily to the right atrium, right ventricle.
Detailed explanation-3: -There are generally three aortic sinuses, one anterior and two posterior sinuses. These give rise to coronary arteries: The left aortic or left posterior aortic sinus gives rise to the left coronary artery. The right aortic or anterior aortic sinus gives rise to the right coronary artery.
