Which part of the heart's conduction system conducts impulses from the AV node to the ventricles?

The Bundle of His, also known as the atrioventricular bundle, plays a crucial role in the heart's conduction system by transmitting electrical impulses from the AV node to the ventricles. Located at the junction between the atria and ventricles, the Bundle of His acts as a pathway for impulses to travel after they are generated at the AV node.

Once an impulse reaches the AV node, it must pass through the Bundle of His to ensure that the ventricles receive the contraction signal necessary for proper heart function. The Bundle of His further splits into right and left bundle branches, which lead to the respective ventricles, ensuring synchronized contraction.

This conduction process is vital for maintaining an effective and coordinated heartbeat, as it allows the atria to contract and fill the ventricles with blood before the ventricles contract. Understanding this pathway helps in grasping how the heart maintains its rhythm and efficiency, which is fundamental in electrocardiography (EKG) studies.
