Occlusion of the left anterior descending artery during a myocardial infarction would interrupt blood supply to which structures?
A)Left and right ventricles and much of the interventricular septum
B)Left atrium and the lateral wall of the left ventricle

D)Posterior interventricular sulcus and the smaller branches of both ventricles

The left anterior descending artery (LAD), also called the anterior interventricular artery, delivers blood to portions of the left and right ventricles and much of the interventricular septum. The circumflex artery supplies the left atrium and lateral wall of the left ventricle. The right coronary artery supplies the right ventricle and one of its branches is the right marginal branch. The interventricular sulcus and smaller branches of both ventricles are also supplied by the right coronary artery.
