Respiratory System, three forms by which carbon dioxide is transported in…

- - - - Nasopharynx, oropharynx, laryngopharynx [*know tissues]
    - - support mucous membrane, increase surface area, bones \ pseudostratified cilicated columnar, goblet cells
    - - thyroid, cricoid, epiglottic \ False and True vocal cords (glottis)
  - - - L & R primary bronchi \ Cilia and goblet cells
    - - [*know the branches] \ connect trachea - alveoli
    - - hilum, Visceral pleura, parietal pleura, pleural cavity
  - - - asbestos, berylliosis, extrinsic allergic alveolitis, air pollution \ bronchial asthma, emphysema
    - - inspiration
        
        atmospheric pressure: 760 mm Hg
        
        Boyle's Law: pressure and volume of gases are inversely proportional
      - expiration
        
        elastic ecoil, surface tension, passive process
    - - pontine respiratory groups
      - medullary respiratory center
        
        ventral
        
        dorsal
    - - wall of alveolus is type 1 cells, simple squamous epithelium \ type 2 cells that secrete pulmonary surfactant
      - structures of respiratory membrane: alveolar wall, blood capillary wall, fused beasement membrane
      - diffusion
    - - The volume of air that enters or leaves the airways and alveoli during a respiratory cycle is called the tidal volume
      - The extra inhaled volume of air after a normal inspiration, when one forcibly continues to inhale, is called the inspiratory reserve volume (IRV)
      - The amount of air that remains in the lungs after a maximal forced expiration is called the residual volume
      - The maximum volume of air a person can exhale after taking the deepest breath possible is called the vital capacity
      - Which lung capacity is calculated by adding the tidal volume (TV), inspiratory reserve volume (IRV), and the expiratory reserve volume (ERV) = VC
      - residual volume + vital capacity (RV + VC) = TLC
      - The volume defined as the maximal amount of air that can be forcefully exhaled beyond the tidal volume is called the expiratory reserve volume (ERV
      - The statement is correct: "the difference in distribution of gases between two areas such as within the alveoli and alveolar capillaries is called the partial pressure gradient
