AV valves
Parts of the atria and the great vessels have been cut. The AV valves guard the openings between the atria and the ventricles. The one on the right side has three cusps and is hence called the tricuspid valve. The one on the left has two cusps and resembles a bishop’s miter, so it is called the mitral/bicuspid valve. Note that the cusps are smooth (no chordae are attached to the atrial surface).
