NEET PG DENTAL EXAM

Detailed explanation-1: -The coronary arteries provide the main blood supply to the heart. The coronary arteries also supply the myocardium with oxygen to allow for the contraction of the heart and thus causing circulation of the blood throughout the body.

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: -The coronary arteries are responsible for carrying nutrient-rich, oxygenated blood from the left ventricle to the myocardium; while the coronary veins take nutrient – poor deoxygenated blood away from the myocardium and to the right atrium.

Detailed explanation-4: -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.
