Aortic Valve
Three-corner semilunar valve (pocket valve) between left ventricle and aorta. It has three crescent-shaped (therefore semilunar) pockets which close off the ventricle to the aorta. These are
- Valvula semilunaris posterior
- Valvula semilunaris dextra
- Valvula semilunaris sinistra
The three pockets are filled by backflowing blood and pressed towards the heart, causing them to lie against each other and function as a valve. The blood cannot flow back into the heart, whose pressure drops in the Diastole and is then lower than that of the aorta.
