Question

Quizplus · Accepted Answer

Chemoreceptors that are involved in reflexive control of respiratory function are primarily sensitive to changes in pH (i.e., acidity) and the partial pressure of carbon dioxide (PCO2) in the blood. Partial pressure of oxygen (PO2) is also important in regulating respiration, but to a lesser extent. However, sodium ion concentration is not a factor in the regulation of breathing by chemoreceptors. Therefore, the correct answer is E.
