Question

Quizplus · Accepted Answer

The chordae tendineae are thin fibrous cords that attach to the cusps of the atrioventricular valves and anchor them to the papillary muscles in the walls of the ventricles during ventricular contraction. This prevents the valve cusps from flipping back into the atria and allows for proper blood flow in one direction.
