ATrabeculae carneae
BModerator bands
CIntercalated discs
DChordae tendineae
Answer & Solution
Correct answer: D. Chordae tendineae
1. Valve flaps need anchoring so they do not blow backward under pressure.
2. The mitral and tricuspid valves connect to papillary muscles via chordae tendineae.
3. Intercalated discs join cardiac muscle cells and are unrelated to valves.
