Quizplus · Accepted Answer

The AV node is located on the floor of the right atrium and is responsible for delaying the electrical impulse before it is transmitted to the ventricles. The SA node is located in the upper right atrium and initiates the electrical impulse. The bundle of His and Purkinje network are located in the ventricles and are responsible for rapidly transmitting the electrical impulse throughout the ventricular muscle.
