It prevents the blood already in the aorta from going back into the heart.
The pulmonary valve is also known as the pulmonic valve, and the aortic valve is simply referred to as the aortic valve.
aortic
Aortic, Bicuspid,tricuspid and Pulmonic valves.
During systole, both atrioventricular valves (tricuspid and mitral) are closed. The aortic valve is open. During diastole, both atrioventricular valves are open, and the aortic valve is closed.
The aortic valve and pulmonary valve are collectively referred to as the semilunar valves due to their semilunar shape. These valves are located between the ventricles and the major arteries of the heart.
Closure of the two atrioventricular valves, specifically the tricuspid and mitral valves.
The aortic valve does that job.
Atrioventricular valves Bicuspid Valve Tricuspid valve Pulmonary valve Aortic valve these are all the valves which are part of the heart.
The aortic pressure increases and the AV valves close.
There are two valves in the heart. They are tricuspid valve and bicuspid valve.There is a possibility of the blood going back into the atria. This is prevented by these two valves, the tricuspid valve on the right side and the bicuspid valve on the left side.Tricuspid ValvePulmonary ValveMitral Valve (AKA Bicuspid Vlave)Aortic ValveThe four valves are known as:The tricuspid valveThe pulmonic or pulmonary valveThe mitral valveThe aortic valve

When the atria contract, there is increase in pressure in the atrial chambers. So both bicuspid and tricuspid valves opened up. When both the ventricles contract, both the bicuspid and tricuspid valves get closed. This opens up the aortic and pulmonary valves.
