Tricuspid valve

Tricuspid valve

The tricuspid valve controls the flow of blood between the upper right chamber of the heart (right atrium) and the lower right chamber (right ventricle). When the heart's right ventricle contracts, the tricuspid valve closes tightly so blood does not leak back into the right atrium.
