Which structure directly follows the AV Node in the cardiac conduction pathway?

Explanation:
The main idea here is the order of the heart’s electrical conduction after the AV node. The AV node relays the impulse to the Bundle of His, which then travels down the interventricular septum into the right and left bundle branches and finally reaches the Purkinje fibers. The Purkinje network is the distribution system that rapidly activates the ventricular muscle, but it comes after the bundle branches, not directly from the AV node. So the structure that directly follows the AV node is the Bundle of His.
