Which of the following statements best describes the function of the chordae tendineae?
A)The chordae tendineae act like a parachute and capture blood as it enters the right ventricle.
B)They pull downward on the valve cusps, thereby preventing the AV valves from being pushed into the atria (prolapsing).
C)The chordae tendineae generate autorhythmicity within the heart.
D)They open and close the AV valve due to the movement of the papillary muscle during contraction.
E)When the heart contracts, the chordate tendineae separate the flow of blood from the right and left sides of the heart.
