Right Coronary Artery supplies blood to which of the following?

The right coronary artery primarily supplies blood to the right side of the heart, including the right atrium, right ventricle, and parts of the interventricular septum. Notably, it plays a crucial role in supplying the right ventricular apex, which is the tip of the right ventricle.

This blood supply is important because the right ventricle is responsible for pumping deoxygenated blood to the lungs for oxygenation. Since the right coronary artery has branches, such as the acute marginal artery, which specifically feed the right ventricular area, it is essential for the overall function of the right ventricle.

In contrast, the left ventricle, interatrial septum, and left atrial wall are predominantly supplied by branches of the left coronary artery, such as the left anterior descending artery and the circumflex artery. Therefore, recognizing the specific territories of coronary artery supply helps in understanding the physiology of the heart and potential areas affected in coronary artery disease.
