Question

How does the delay of the impulse at the atrioventricular node contribute to cardiac function?

Answer 1

Answer:

Hey there this is your answer..!!!

The atrioventricular node delays impulses by approximately 0.09s. This delay in the cardiac pulse is extremely important: It ensures that the atria have ejected their blood into the ventricles first before the ventricles contract.

hope this helps you..!!!
