Quizplus · Accepted Answer

The atrioventricular (AV) valve is not part of the intrinsic conduction system of the heart. The intrinsic conduction system refers to a specialized network of cells and fibers that initiate and distribute electrical impulses throughout the heart to ensure coordinated contractions. The SA node serves as the pacemaker of the heart, initiating each heartbeat. The AV node delays the electrical impulse to allow for the atria to fully contract before the ventricles contract. The bundle branches transmit the impulse to the Purkinje fibers, which distribute the impulse to the ventricles for contraction.
