Question

Quizplus · Accepted Answer

The aortic semilunar valve is located between the left ventricle and the aorta. Its function is to prevent blood from flowing back into the left ventricle from the aorta after the left ventricle contracts and pumps blood into the aorta. If this valve is incompetent, it would allow blood to backflow from the aorta into the left ventricle.
