Detailed explanation-1: -Your aortic valve opens to let blood flow from your left ventricle to your aorta. It closes to prevent blood from flowing in the wrong direction. The closed valve keeps blood from leaking from your aorta back into your heart.
Detailed explanation-2: -Aortic Valve Opens to allow blood to leave the heart from the left ventricle through the aorta and the body.
Detailed explanation-3: -When the left ventricle contracts, it forces blood through the aortic semilunar valve and into the aorta. The aorta and its branches carries the blood to all the body’s tissues.
Detailed explanation-4: -The semilunar valves act to prevent backflow of blood from the arteries to the ventricles during ventricular diastole and help maintain pressure on the major arteries. The aortic semilunar valve separates the left ventricle from the opening of the aorta.
