During ventricular contraction, chordae tendineae supports
-
tricuspid valve
-
bicuspid valve
-
Both 1 and 2
-
None of the above
C
Correct answer
Explanation
Chordae tendineae are fibrous cords that connect the AV valve cusps to the papillary muscles in the ventricles. During ventricular contraction (systole), they prevent the tricuspid and bicuspid (mitral) valves from prolapsing into the atria by resisting the high pressure generated.
