Use the following answer code to compare the magnitude of the items in question.
-A. Spontaneous rate of depolarization in the SA node
B. Spontaneous rate of depolarization in the ventricles
A)A is greater than B
B)B is greater than A
C)A and B are equal

Question

Quizplus · Accepted Answer

The SA node is responsible for initiating the electrical impulses that regulate heart rate. The spontaneous depolarization rate of the SA node is typically around 60-100 times per minute, while the ventricles typically depolarize at a slower rate of around 20-40 times per minute. Therefore, A is greater than B.
