This one is called the tricuspid valve, and it allows blood into the right ventricle.

三尖瓣让血液得以进入右心室。

When the ventricle is filled, it contracts, forcing the tricuspid valve to close and forcing the blood through the pulmonary semilunar valve on its way to the lungs.

心室充盈时，收缩，迫使三尖瓣关闭，迫使血液通过肺半月瓣进入肺部。
