The chordae tendineae (a) close the atrioventricular valves, (b) prevent the AV valve flaps from everting, (c) contract the papillary muscles, (d) open the semilunar valves.

The function of the chordae tendineae is to pull the walls of the ventricles inward during contraction open the semilunar valves open the AV valves prevent eversion of the AV valves during ventricular systole hold the heart in place within the mediastinum;

Which of the following statements is CORRECT concerning the mitral valve? Pectinate muscles help open this valve by pulling down on the chordae tendineae. This valve closes when pressure in the left ventricle exceeds that of the left atrium. The papillary muscles open this valve by pushing on the chordae tendineae. This valve opens when pressure in the right atrium exceeds that of the right ventricle.
