The papillary muscles and the chordae tendinae work to prevent prolapse of the AV valves. This prevents backflow of blood in the heart.
Chordae tendineae are associated with the heart, specifically with the atrioventricular valves (tricuspid and mitral valves). They are fibrous cords that attach the valves to the papillary muscles in order to prevent the valves from inverting into the atria during ventricular contraction.
To ensure that the AV valves do not evert (turn inside-out), they are attached to (anchored by) small papillary muscles by tough tendons called the cordae tendineae or chordae tendineae cordis.
The chordae tendinae are connected to the atrioventricular valves. These are the valves that separate the atrium from the ventricle on each side of the heart.
