Does chordae tendineae prevent backflow
WebWhat is the function of the chordae tendineae and papillary muscles of the bicuspid and tricuspid valves. a) preventing reflux ( regurgitation) of ventricular blood into the … WebThe names bi- and tricuspid are derived from the number of cusps or flaps that make up the valve. A closer look at these valves reveals that they are supported by small tendon-like attachments called chordae tendineae, which attach the edges of the valves to small nipple-like projections of muscle called papillary muscles.
