SpletVentilation is influenced and regulated by chemoreceptors for Pa CO 2, PaO 2, and pH located in the brainstem, and in the aortic and carotid bodies as well as by neural impulses from lung stretch receptors and impulses from the cerebral cortex. Failure of ventilation quickly increases the Pa CO 2 . SpletChemoreceptors. Peripheral chemoreceptors ( carotid and aortic bodies) and central chemoreceptors (medullary neurons) primarily function to regulate respiratory activity.
