Which artery supplies blood to the right atrium and parts of both ventricles?

The right coronary artery is responsible for supplying blood to the right atrium and parts of both ventricles. This artery branches off from the aorta and provides essential blood flow to the right side of the heart. In most individuals, it also supplies the inferior part of the left ventricle and the right ventricle, making it crucial for proper cardiac function and maintenance of myocardial tissue health.

The left coronary artery primarily supplies the left atrium and the left ventricle, while the anterior interventricular artery, which is a branch of the left coronary artery, focuses on the anterior wall of the left ventricle. The circumflex artery, another branch of the left coronary artery, generally supplies the lateral and posterior aspects of the left ventricle. None of these arteries provide blood flow to the right atrium, highlighting the unique role of the right coronary artery in the overall cardiac circulation.
