Higher pressure on the convex side (from the heart contracting) than the concave side causes them to open. When the pressure reverses (the heart relaxes) they close.

What valve is at the entrance to the aorta?
The heart pumps blood from the left ventricle through the aortic semilunar valve into the Aorta.
What heart valve is located between the left ventricle and the aorta?
the aortic valveThe Aortic valveThe aortic semilunar valve lies between the left ventricle and the aorta.
How do you auscultate the aortic semilunar valve?
The aortic semilunar valve is auscultated by placing a stethoscope next to the sternum in the second intercostal space.
What comes after the aortic semilunar valve?
The blood flows through the aorta after exiting the left ventricle through the aortic valve.
What valve prevents blood back flow from aorta to left ventricle?
Pulmonary semilunar valve (pulmonary valve)
Why does the aortic semilunar valve close?
All the heart valves close in order to prevent the back flow of blood, including semilunar valve.

This heart chamber pumps blood through the aortic semilunar valve?
pulmonary semilunar valve

Pulmonary semilunar valve (pulmonary valve)
Valve preventing backflow into ventricles?
there r two valves: aortic semilunar valve and pulmonary semilunar valve
What valve is the gatekeeper to the systemic circuit?
Aortic Semilunar Valve
What event results in the pressure deflection called the dicrotic notch?
When the aortic semilunar valve snaps shut, a momentary increase in the aortic pressure results from the elastic recoil of the aorta after valve closure.
