Which of the following is correct about the right coronary artery? Perfuses the Left Ventricle. Perfuses the SA node in 45% of the population. Perfuses the Left Atrium. Does not perfuse the AV node in 10% of the population.

The correct statement about the right coronary artery is:<br /><br />**Perfuses the SA node in 45% of the population.**<br /><br />The right coronary artery (RCA) supplies blood to the right atrium, right ventricle, and portions of the conduction system, including the sinoatrial (SA) node in approximately 45% of individuals. The other statements are incorrect:<br /><br />- The RCA does not perfuse the left ventricle; this is typically the role of the left coronary artery (LCA).<br />- The RCA does not perfuse the left atrium; this is also supplied by branches of the LCA.<br />- The RCA perfuses the atrioventricular (AV) node in the majority of individuals, not 10%.
