What is the function of the aortic valve?
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.

What Functions of the valves in the heart?
there is the bicuspid valve which opens up to allow oxygenated blood into the heart after the oxygenated blood has entered the heart, i closes to prevent flowback of the blood, then the semi lunar valve opens up which allows the deoxygenated blooto exit, and once it has exited, it closes for the same reason which is to prevent flowback. so basically it is to prevent the flowback of blood
