Coronary Arteries
The two main divisions for coronary arteries are the right and left coronary arteries.
The right coronary artery feeds the right atrium, right ventricle and inferior portions of the heart.
The left Main Coronary Artery feeds the anterior descending and circumflex coronary arteries.
The Left Anterior Descending, or LAD, supplies the anterior portion of the left ventricle and most of the interventricular septum.
The Circumflex supplies the left atrium, lateral portion of the left ventricle.
