WebbPulmonary stretch receptors are thought to mediate the breathing frequency (bf) response to changes in pulmonary CO2. However, the location and distribution of these receptors is disputed. The purpose of this study was to determine what contribution the extrapulmonary receptors make in the pulmonary CO2 bf response.
