The correct order of the conduction system of the heart is SA node (sinoatrial node), AV node (atrioventricular node), bundle of His, and Purkinje network. The SA node is the natural pacemaker of the heart and initiates the electrical impulses that regulate the heartbeat. The impulses then travel to the AV node, which slows down the electrical signal before it reaches the ventricles. From the AV node, the impulses travel through the bundle of His and then the Purkinje network, which transmit the impulses rapidly through the ventricular muscle, causing it to contract and pump blood out of the heart.
