What is the importance of the delay in the action potential in the AV node?
A)It allows the action potential to reach both ventricles at the same time.
B)It allows an action potential to reach the left atrium so both atria contract together.
C)It allows an action potential to reach the left atrium so both atria contract together,before the ventricles contract.
D)It allows time for the atria to be filled with blood.

Question

Quizplus · Accepted Answer

The delay in action potential in the AV node allows enough time for both the atria to contract together before the signal reaches the ventricles. This ensures maximum atrial filling, leading to an effective ventricular filling and contraction, resulting in efficient pumping of blood into the arteries.
