What is the function of chordae tendineae?
Show answer and explanation
Correct answer: Preventing AV valve cusps from everting into the atria
Chordae tendineae are 'heart strings' attached to the cusps of the bicuspid and tricuspid valves and anchored to papillary muscles. They prevent the AV valve cusps from being pushed back (everted) into the atria during powerful ventricular contractions.
