- - - - Volume Decreases = Pressure Increases
      - Volume Increases = Pressure Decreases
  - - - LOW temp. gases = MORE soluble
      - HIGH temp. gases = LESS soluble
  - - - pressure exerted by a gas = % of that gas to gas mixture
- - - - carried in RBC's as carbaminohemoglobin
        
        rapid reaction
  - - - CO2 enters plasma and then RBC's quickly
        
        combines with water
        
        forms bicarbonate and hydrogen ion
        
        bicarbonate diffuses into plasma
        
        rbc's into plasma where it is carried to lungs
- - - - posterior to nasal cavity & superior to the soft palate
        
        pseudostratified ciliated epithelium
  - - - Posterior to epiglottis and extends to the larynx
- - - - integrates input from peripheral sensory input and modifies rhythms generated by the VRG
  - - - Inspiratory neurons fire!
        
        burst of impulses travels among the phrenic and intercostal nerves
        
        excite diaphragm and external intercostal muscles
        
        thorax expands and inspiration occurs!
        
        VRG's expiratory neurons fire!
        
        output stops!
        
        expiration occurs
        
        inspiratory muscles relax and lungs recoli
- - - - Subdivides into Lobar (secondary) bronchi
        
        Segmental (tertiary) bronchi
        
        Terminal Bronchioles
        
        Respiratory Bronchioles
        " where the actual respiration happens!"
        Respiratory Zone starts HERE!
        
        Alveolar ducts
        
        alveolar sacs
- - - - Presence of Hemoglobin
        
        iron of hemoglobin attaches O2
        
        98% of O2 in blood is bound to hemoglobin
        
        oxyhemoglobin (oxygen bound)
        
        deoxyhemoglobin (w/o O2)
- - - - posterior to external nose
        
        divided by nasal septum
        
        paranasal sinuses
        
        mucosa-lined, air filled cavities in cranial bones
        
        Sinusitis = inflamed sinuses
