Sep 12, 2022 · Carotid bodies are sensitive to changes in PaO2 or pH, and the respiratory center responds with a change in respiratory rate and volume. Feedback from stretch receptors of muscles, tendons, and joints about the elastic recoil of the lung and the thoracic wall modifies the respiratory rate so that the lung optimizes the respiratory work, maximizes the gas exchange, and minimizes the mechanical ...
