The central chem oreceptors respond to A) P_CO2 in the CSF B) P_O2 in the CSF C) pH in the CSF D) Temperature of the CSF E) Both A and C

Question

Quizplus · Accepted Answer

Central chemoreceptors primarily respond to changes in the partial pressure of carbon dioxide (CO2) and the pH of the cerebrospinal fluid (CSF), not directly to oxygen levels or temperature. An increase in CO2 leads to a decrease in pH, which stimulates these receptors to induce corrective mechanisms to normalize these parameters.
