A key influence of the location of the atrioventricular node on the heartbeat is to
A)speed up the conduction of the electrical impulse to contract as it passes from the atria to the ventricles.
B)slow down the conduction of the electrical impulse to contract as it passes from the atria to the ventricles.
C)act as a barrier that prevents the conduction of the electrical impulse to contract as it passes from the atria to the ventricles.
D)not alter the speed at which the electrical impulse to contract passes from the atria to the ventricles.
E)block backflow of blood from the aorta into the right ventriclE.

Question

Quizplus · Accepted Answer

The location of the atrioventricular (AV) node acts as a natural gatekeeper between the atria and ventricles. It slows down the conduction of the electrical impulse passing from the atria to the ventricles, allowing for coordinated contractions and efficient pumping of blood. This delay ensures that the atria empty their contents into the ventricles before the ventricles contract, preventing inefficient backflow of blood.
