Question

Quizplus · Accepted Answer

The Bundle of His and Purkinje system are responsible for rapidly conducting the electrical impulse down the ventricular septum and throughout much of the ventricular musculature. The SA and AV nodes play a role in the initiation and coordination of cardiac excitation, while gap junctions allow for the flow of ions and electrical signals between adjacent cardiac cells.
