Answer:
D The atrioventricular valve works as a rigid door to prevent water from escaping from the top.
Explanation:
the question is incomplete, but I annex the options and their explanation
When you compress the heart in this demo, why does the water leave the artery?
A It's like squeezing a sponge
B The arterial valve draws water from the ventricle.
C The atrioventricular valve has parachute-shaped fins to prevent water from escaping from the top.
D The atrioventricular valve works as a rigid door to prevent water from escaping from the top.
the atrioventricular valve during the contraction process closes at the top, thus avoiding the leakage of the liquid and leaving the artery that opens due to the force exerted by the volume and force of the ventricle.
