Explanation:
Detailed explanation-1: -The chordae tendinae (CT) are strong, fibrous connections between the valve leaflets and the papillary muscles . These are attached to the leaflets on to the ventricular side and prevent the cusps from swinging back into the atrial cavity during systole.
Detailed explanation-2: -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.
Detailed explanation-3: -The papillary muscles are “nipple” like projections of the myocardia and contract when the myocardia contracts. As a result, they pull on the chordae tendinae and help to prevent prolapsing of the AV valves.
