Detailed explanation-1: -The aortic and pulmonic valves close preventing backward blood flow into the heart. The mitral and tricuspid valves then open to allow forward blood flow within the heart to fill the ventricles again.

Detailed explanation-2: -Atrioventricular valves are anchored by the chordae tendinae that extend from the leaflets down to the papillary muscles within the ventricle walls, preventing the valves from inverting.

Detailed explanation-3: -Tricuspid valve: This valve has three leaflets. They allow blood to flow from the right atrium to the right ventricle. They also prevent blood from flowing backward from the right ventricle to the right atrium.
