Hypoventilation that results in the retention of carbon dioxide will stimulate which receptors in an attempt to maintain a normal homeostatic state?
A)Irritant receptors
B)Central chemoreceptors
C)Peripheral chemoreceptors
D)Stretch receptors

Question

Quizplus · Accepted Answer

Central chemoreceptors indirectly monitor arterial blood by sensing changes in the pH of cerebrospinal fluid (CSF). The central chemoreceptors are sensitive to very small changes in the pH of CSF (equivalent to a 1 to 2 mmHg change in partial pressure of carbon dioxide [PCO₂]) and are able to maintain a normal partial pressure of arterial carbon dioxide (PaCO₂) under many different conditions, including strenuous exercise. The retention of carbon dioxide will not stimulate irritant receptors, peripheral chemoreceptors, or stretch receptors.
