B)AV node
C)ventricles
D)atria

Question

Quizplus · Accepted Answer

The AV node has the slowest conduction speed among the conduction system, which is necessary for ensuring the proper coordination of atrial and ventricular contractions. This delay allows the atria to contract fully before the ventricles receive the signal to contract.
