Explanation:
Detailed explanation-1: -The SA (sinoatrial) node generates an electrical signal that causes the upper heart chambers (atria) to contract. The signal then passes through the AV (atrioventricular) node to the lower heart chambers (ventricles), causing them to contract, or pump.
Detailed explanation-2: -Thus, the correct answer is ‘SA Node, AV node, AV Bundle, Purkinje fibre.
