The heart’s main supply line, the coronary arteries, provide vital blood flow to the heart muscle. The left main coronary artery, a crucial junction, supplies the left ventricle, the heart’s most critical pumping chamber. The LAD and LCX arteries nourish the anterior and posterior walls of the left ventricle. The RCA serves multiple areas, including the right ventricle and sinus node. The marginal and PDA arteries supply blood to the lateral and inferior regions of the heart’s posterior wall. These arteries ensure an uninterrupted supply of oxygen and nutrients to the heart, enabling its constant pumping function.
