Detailed explanation-1: -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-2: -Where are the coronary arteries located? Your coronary arteries are around and inside your heart muscle. They branch off your aorta, which is the main artery in your body. They start at the aortic root, which is the first part of your aorta that emerges from the left ventricle of your heart.
