Heart Valves and function
The heart, a muscular organ roughly the size of a clenched fist, serves as the central pump of the circulatory system in most animals, including humans. The movement of blood through heart is unidirectional. This unidirectional movement is regulated by this valves. These valves prevents backflow of blood to different chambers of the heart.

1. Tricuspid Valve:
- Situated between the right atrium and right ventricle,
- Preventing backflow of blood into the atrium during ventricular contraction.
- It has three leaflets.
2. Pulmonary Valve:
- Situated between the right ventricle and pulmonary artery.
- Allow blood to pump from the right ventricle to the pulmonary artery.
- Prevents backflow and has 3 leaflets
These two valves are involved in regulating the movement of oxygen poor blood through heart.
3. Mitral Valve:
- Located between the left atrium and left ventricle
- Preventing backflow of blood into the atrium during ventricular contraction.
- It has two leaflets.
4. Aortic valve :
- situated between the left ventricle and the aorta.
- responsible for regulating blood flow from the heart into the aorta during contraction and preventing backflow during relaxation.
- It has 3 leaflets
These two valves are involved in regulating the movement of oxygen rich blood heart.
