Receptors responsive to the removal of carbon dioxide from ventilatory gas were demonstrated in the lungs of the chicken. Apnea was induced in 0.64 second after rapid lowering of respired carbon dioxide in the absence of blood flow through the lungs. Afferent impulses from the receptors are conducted centrally in the vagi.
