The tricuspid valve and bicuspid valve (mitral valve) are attached to the right and left ventricle respectably by strong, elastic threads known as chordae tendineae.
Figure: L.S of the left heart chamber showing the chordae tendineae.
The functions of the chordae tendineae:
Chordae tendineae maintain the position and tension of the atrioventricular valves (tricuspid and bicuspid valves).
They maintain the one-way blood flow from the auricle to the ventricles.
