Detailed explanation-1: -The RCA supplies blood to the right side of the heart. The sinoatrial nodal branch of the RCA provides blood to the SA node, and the atrioventricular nodal artery delivers blood to the AV node. The marginal branch of the right coronary artery provides blood supply to the lateral portion of the right ventricle.
Detailed explanation-2: -CORONARY ANATOMY The first RCA branch is the conus branch, which supplies the myocardium of the right ventricular outflow tract (RVOT).
Detailed explanation-3: -The inferior interventricular (descending) branch (also commonly referred to as the posterior descending artery (PDA)) is the largest of these branches, and descends in the inferior interventricular groove. On its course, it supplies the interventricular septum and adjacent surfaces of both ventricles.
