Quizplus · Accepted Answer

The left anterior descending artery is a coronary artery that supplies blood to the left ventricle of the heart. It is not part of the systemic circulation that flows from the venae cavae to the pulmonary veins. Therefore, it is not perfused during this process. The right ventricle, pulmonary artery, and pulmonary capillaries are all perfused during this circulation.
