A leaking aortic valve means that when your hears pumps blood through the valve, that the valve does not close of properly when it should. This causes your heart to have to work harder because some of the blood it pumps leaks back into the heart and needs to be pumped out again.
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.
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 heart pumps blood from the left ventricle through the aortic semilunar valve into the Aorta.
the aortic valveThe Aortic valveThe aortic semilunar valve lies between the left ventricle and the aorta.
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

The aortic semilunar valve is located between the left ventricle and the aorta.
Aortic stenosis
The Aortic Valve controls the flow of blood from the left ventricle to the aorta.
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.
lol i had the same worksheet. the answer is the aortic valve. i just put down aortic
