NEET PG DENTAL EXAM

Detailed explanation-1: -The right and left coronary arteries supply blood to your heart. They’re the first branches off the aorta, which is the main artery in your body. These arteries and their branches supply all parts of the heart muscle with blood.

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 conus artery is the first provided branch by the RCA; it originates from the ostium of the RCA or separately from the right coronary sinus and has a superior and anterior course. It supplies the right ventricle.

Detailed explanation-4: -Two main coronary arteries originate from the base of the aorta as it exits the left ventricle: the left and right coronary arteries. These arteries further branch into smaller arteries to supply specific parts of the heart like the atria, ventricles, SA, and AV nodes.
