    low adaptations to maximize exchange

          

  4. sets basic rhythm

    monitors CO2 levels via pH (blood & cerebrospinal fluid)

    negative feedback system via pulmonary stretch receptors prevent lung over inflation

  5. trachea

    bronchi

    bronchioles

    alveoli

    ciliated epithelium
