What kind of supplies are linked to the Right Coronary Artery?

The Right Coronary Artery (RCA) primarily supplies blood to the inferior and posterior walls of the heart. This artery originates from the right side of the aorta and travels along the right atrioventricular (AV) groove towards the right side of the heart.

The inferior wall of the heart is perfused by the RCA through its branches, specifically the right posterior descending artery, which ensures adequate blood flow to this region during the cardiac cycle. Additionally, the RCA's supply to the posterior wall is critical for maintaining healthy myocardial function in that area, especially in right-dominant coronary systems, where the RCA provides the majority of blood supply to the inferior wall.

The other choices reference areas of the heart that are primarily served by other arteries, such as the left coronary artery and its branches. This distinction reinforces the knowledge related to coronary anatomy and the specificity of blood supply through different coronary vessels. Understanding this supply is crucial for diagnosing and managing conditions related to coronary artery disease and overall cardiac health.
