The valves prevent the backward flow of blood. These valves are actual flaps that are located on each end of the two ventricles (lower chambers of the heart). They act as one-way inlets of blood on one side of a ventricle and one-way outlets of blood on the other side of a ventricle.

What is the function of the valves in the heart?
Blood passes through a valve before leaving each chamber of the heart. The valves prevent the backward flow of blood. Valves are actually flaps (leaflets) that act as one-way inlets for blood coming into a ventricle and one-way outlets for blood leaving a ventricle.
What is the name of valve?
Structure
| Valve | Number of flaps/cusps | location |
|---|---|---|
| Atrioventricular valves | 3 or 2 | |
| Tricuspid valve | 3 | between the right atrium and right ventricle. |
| Bicuspid or mitral valve | 2 | between the left atrium and left ventricle. |
| Semilunar valves | 3 (half-moon shaped) flaps |
What are the four heart valves and their functions?
The heart has 4 valves:
- The mitral valve and tricuspid valve, which control blood flow from the atria to the ventricles.
- The aortic valve and pulmonary valve, which control blood flow out of the ventricles.
Where are the 4 heart valves located?
The heart has four valves. The mitral valve, the tricuspid valve, the pulmonary valve and the aortic valve. The mitral and the tricuspid valves, also known as the atrioventricular valves, are located between the top chambers of the heart, the atria, and the lower chambers of the heart, the ventricles.
