Question

Quizplus · Accepted Answer

The function of the atrioventricular node is to delay the electrical impulses sent from the atria to the ventricles, allowing time for the atria to fully contract before the ventricles begin to contract. This prevents the atria and ventricles from contracting simultaneously, which would lead to inefficient pumping of blood.
