What is the structure and function of the heart valve?

Leaflets, flow cont.: Heart valves are made of fibrous tissues that are supported in the case of tricuspid and mitral valves with muscles and apparatus that work as a unit. These generally work as check valves, allowing the flow of blood in one direction only and not backwards.

Depends: It depends on the valve. There are 4 of them and they're all different.
