Valves regulate floe of blood by opening on one side to let blood flow out in one direction and prevent back flow of blood.

There are 4 valves present in heart

Tricuspid valve → It is present between right artrium and right ventricle. It prevent back flow of blood into right artrium.

Pulmonary Valve → Present between right ventricle and pulmonary artery.

Mitral Valve → Present between left artrium and left ventricle.

Aortic Valve → Present between left ventricle and Aorta
