The aortic valve functions as a one-way valve between the heart and the rest of the body. Blood is pumped from the left ventricle of the heart, through the valve, and down the aorta, which in turn supplies blood to all of the organs in the body. Between heart contractions, the valve closes, preventing blood from flowing backwards into the heart. The function of the aortic valve is then twofold: (1) It provides a route for which blood can leave the heart, and (2) It prevents blood that has already left the heart from leaking backwards into the heart.
Aortic stenosis
The left ventricle discharges its blood through the aortic valve.
The aortic semilunar valve prevents backflow of blood from the aorta to the left ventricle.The aortic valve prevents backflow of blood from the aorta to the left ventricle of the heart.aortic valve
It's where the Aortic Vavle is diseased by narrowing of the Vavle or thickening of the tissue.
To prevent blood from flowing back into the left ventricle.
The Aortic Valve controls the flow of blood from the left ventricle to the aorta.
The aortic valve helps with the process of pumping blood from the left ventricle to the aorta. It prevents the blood from going back to the left ventricle from the aorta.
Aortic valve replacement is necessary when the aortic valve has become diseased. The aortic valve can suffer from insufficiency (inability to perform adequately) or stenosis.
the aortic valveThe Aortic valveThe aortic semilunar valve lies between the left ventricle and the aorta.
The heart pumps blood from the left ventricle through the aortic semilunar valve into the Aorta.
The two semiluar valves are at the exits from the ventricles the pulmonary valve between the right ventricle and the pulmonary artery and the aortic valve between the left ventricle and the aorta. This means that their function is to assist the heart valves to control blood flow.
The blood flows through the aorta after exiting the left ventricle through the aortic valve.
because the aortic valve is not functioning properly, i.e. prolapse

If she is concerned about this she should speak to a physician. Aortic valve replacement may be necessary if her aortic valve has narrowed or is leaking.
The aortic semilunar valve is located between the left ventricle and the aorta.
