A-V Node and Cardiovascular Fibers

Explanation:
Detailed explanation-1: -The SA node (physiologicalpacemaker) starts the sequence by generating an electrical impulse, causing the atrial muscles to contract. From there, the signal travels to the AV node, then through the bundle of His, down the bundle branches, and through the Purkinje fibers, causing the ventricles to contract.
Detailed explanation-2: -Thus, the correct answer is ‘SA Node, AV node, AV Bundle, Purkinje fibre.
Detailed explanation-3: -The sino-atrial (SA) node. The atrio-ventricular (AV) node. The bundle of His. The left and right bundle branches. The Purkinje fibres.
