<prompt> Peripheral central chemoreceptors may both contribute to increased ventilation that occurs as a result of decreasedAerial BPAerial tensionAerial O2 concentrationH  <response>: The central chemoreceptors monitor the H concentration of cerebrospinal fluid CSF, including the brain interstitial fluid.The receptors in the carotid and aoic bodiesperipheral chemoreceptors are stimulated by a rise in the PCO2 or H concentration of aerial blood or a decline in its PO2.Ref: Ganongs Review of Medical Physiology, Twenty-Third Edition, Page number: 627, 628
