The chordae tendineae
A) connect the atria to the ventricles.
B) are found in the interventricular septum.
C) are part of the conducting system of the heart.
D) connect the cusps of the AV valves to the papillary muscles.
E) are a part of the myocardium.
Chordae Tendineae
Strong, fibrous strings attached to the heart's ventricular walls and the cusps of the atrioventricular valves, playing a crucial role in heart function.
Papillary Muscles
Muscular projections in the heart ventricles that attach to the cusps of the atrioventricular valves via the chordae tendineae, playing a role in valve function.

Final Answer :
D
Explanation :
The chordae tendineae connect the cusps of the atrioventricular (AV) valves (mitral and tricuspid valves) to the papillary muscles in the heart. This connection helps prevent the AV valves from inverting when the ventricles contract, ensuring that blood flows in the correct direction from the atria to the ventricles.
