When central chemoreceptors detect a drop in the pH of the cerebrospinal fluid,
A) medullary respiratory centers trigger an increase in rate and depth of breathing.
B) medullary respiratory centers trigger a decrease in rate and depth of breathing.
C) pontine respiratory centers trigger a decrease in rate and depth of breathing.
D) the vagus and phrenic nerves stimulate decreased production of the catalyst carbonic anhydrase.

Question

Quizplus · Accepted Answer

Central chemoreceptors respond to a drop in pH by signaling the medullary respiratory centers to increase the rate and depth of breathing to expel more CO2, which helps raise the pH back to normal.
