Question

Quizplus · Accepted Answer

Chordae tendineae are responsible for preventing the cusps of the AV valves (tricuspid and mitral) from swinging into the atria during ventricular contraction. Malfunctioning chordae tendineae can cause the valves to not close properly, resulting in regurgitation of blood back into the atria. This can lead to heart murmurs and other complications. Malfunctioning chordae tendineae would not allow blood to flow back into the aorta and pulmonary trunk (A), inhibit closure of the semilunar valves (B), enable the cusps of the AV valves to swing into the ventricles (D), or block blood flow into coronary arteries (E).
