Which artery supplies the inferior wall of the heart?

The artery that supplies the inferior wall of the heart is indeed the Right Coronary Artery. This artery typically provides circulation to the right atrium, right ventricle, and the inferior part of the left ventricle via the posterior descending artery, which branches off from it in most individuals. The inferior wall of the heart is primarily affected by any issues related to the right coronary artery, especially in terms of blood flow and potential infarctions.

In a normal right dominant coronary system, the right coronary artery gives rise to the posterior descending artery, which supplies the inferior wall. The other arteries listed are primarily responsible for supplying different portions of the heart; for instance, the Left Circumflex artery mainly supplies the lateral and posterior walls of the left ventricle, the Left Anterior Descending artery supplies the anterior wall and interventricular septum, and the Left Main Coronary Artery bifurcates into the left circumflex and left anterior descending arteries. Therefore, focusing on which artery provides the necessary blood supply to the inferior region leads us to the correct choice of the Right Coronary Artery.
