The correct answer is B) Chordae tendinae. These fibrous cords connect the AV valves (mitral and tricuspid) to the papillary muscles in the ventricles, playing a crucial role in preventing backflow of blood when the heart contracts. Imagine them as tiny strings on a puppet that keep everything in its place!
In your heart’s orchestra, when the ventricles contract, the papillary muscles pull the chordae tendinae taut, ensuring the valves close properly. If these tendons were to fail, it could lead to a heart that’s a bit off-key, causing valve prolapse and potentially significant health concerns! So, let’s keep those chords in tip-top shape!
