Use the following answer code to compare the magnitude of the items in question.
-A. velocity of impulse through the bundle of His and Purkinje system
B. velocity of impulse conduction through the AV node
A)A is greater than B
B)B is greater than A
C)A and B are equal

Question

Quizplus · Accepted Answer

The bundle of His and Purkinje system is responsible for rapid conduction of impulses through the ventricles of the heart, so the velocity of impulse through it is faster than the AV node, which acts as a gatekeeper to regulate the impulse transmission from the atria to the ventricles. Therefore, A is greater than B.
