Structure. The tricuspid valve has a complex structure composed of several components: Leaflets: The valve typically has three cusps or leaflets, named the anterior, posterior, and septal leaflets, according to their position.These leaflets are thin, flexible flaps of tissue that open and close to regulate blood flow.
The cusps are pushed open to allow blood flow in one direction, and then closed to seal the orifices and prevent the backflow of blood. Backward prolapse of the cusps is prevented by the chordae tendineae–also known as the heart strings–fibrous cords that connect the papillary muscles of the ventricular wall to the aventricular valves.. …
