The chordae tendineae, or heart strings, are cord like structures that connect the Mitral and tricuspid valve to the papillary muscles. The functions of chordae tendineae are: 1) bring the right ventricular walls closer together during contraction. 2) pull the semilunar valves open to allow ventricular ejection.
prevent relapse of valve cusps into atria (when the ventricles and papillary muscles contract the chordae tendonae are pulled tight preventing prolapse of valve cusps/leaflets into the atria). what is the function of chordae tendonae.
