Study Notes
Atrioventricular Valves in the Heart
- Atrioventricular valves prevent backflow of blood from the ventricles to the atria.
- They ensure blood flows in one direction, from the atria to the ventricles.
Tricuspid Valve
- The tricuspid valve has three leaflets.
Chordae Tendineae
- Chordae tendineae are thin, fibrous cords that connect the heart valves to the ventricular walls.
- They prevent the valves from bulging too far into the ventricles and prolapsing.
Left Atrioventricular Valve
- The left atrioventricular valve is a bicuspid valve, also known as the mitral valve.
Papillary Muscles
- Papillary muscles are small, finger-like muscles that project from the ventricular walls.
- They contract to pull the chordae tendineae, which in turn, pull the valve cusps together to prevent regurgitation of blood.
