The function of the ventricular conduction system of the heart is to
A)spread the action potential throughout the ventricle to ensure a single, coordinated contraction of the both ventricles
B)spread the action potential in the absence of sympathetic stimulation
C)spread the action potential throughout the atria and ventricles
D)slow down the original action potential so it has time to spread through the ventricles evenly
E)perform both a and d
