THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The RCA gives rise to the sinoatrial nodal branch of the right coronary artery, posterior descending artery branch of the RCA, and the marginal branch. The LMCA branches into the circumflex and LAD. The circumflex artery gives rise to the left marginal artery and posterior descending artery (in a left-dominant heart).

Detailed explanation-2: -It gives off many branches, including the sinoatrial nodal artery, right marginal artery, posterior interventricular artery, conus artery, and atrioventricular nodal branch. It contributes the right side of the heart, and parts of the interventricular septum.
