What are the valves called?

Valves are typically referred to by their specific types, such as "atrioventricular valves" (which include the tricuspid and mitral valves) and "semilunar valves" (which include the aortic and pulmonary valves) in the heart. In other contexts, valves can be named according to their function, such as "check valves," "ball valves," or "gate valves" in Plumbing and industrial applications. Each type serves a distinct purpose in regulating the flow of fluids or blood.
