It is named this because it has three leafl ets. It is a one way valve, which commonly ! only allowing blood to travel from the right atrium to the right ventricle. in that location are authorized conditions where the flow can reverse. This being called tricuspid regurgitation (rejection), barely this is not normal. This can cause a distinctive mumble if you were to listen to it flowing backwards.
