The component of the heart’s electrical conduction system

Identify the component of the heart’s electrical conduction system that fits each description below: a. Establishes the basic heart rate: the SA node b. Delays action potential, letting the atria and ventricles contract separately: _bundle branches c. Conduct action potential through interventricular septum: d. Directly brings action potential to contractile cells of the heart
