Final answer:

Chordae tendineae are essential for preventing backflow through the atrioventricular valves, working in conjunction with papillary muscles to maintain proper valve function.


Explanation:

Chordae tendineae are string-like extensions of tough connective tissue that extend from the flaps of the atrioventricular valves to the papillary muscles. They play a crucial role in preventing backflow of blood through the atrioventricular valves during ventricular contraction. The papillary muscles contract in coordination with the pressure changes in the ventricles to maintain tension on the chordae tendineae and ensure proper valve function.
