- - - - trachea
        
        carnia
        
        primary bronchi
        
        secondary bronchi
        
        tertiary bronchi
        
        terminal bronchioles

        heart
  - - - Pleurisy
  - - - left
- - - - first place air gets too
      - trachea
        
        air travels down from here
        
        carnia
        
        trachea meets this, bronchi begins
        
        primary bronchi
        
        right and left, right more likely for something to be stuck because it more straight.
        
        secondary bronchi
        
        come off of primary bronchi, start branching out
        
        tertiary bronchi
        
        branch off secondary bronchi
        
        terminal bronchioles

  - - - when oxygen reaches the alveoli, oxygen diffuses through the membrane and get into the capillaries(external respiration) to get onto the deoxygenated rbc.
      - lung
        
        send blood to get oxygenated from the process above.
        
        heart
        
        blood comes back to heart, to be then sent out to rest of the body. For example if you are running away from a bear. Your legs need are gonna be in high need of oxygen. So whats going to happen is rbc are in capillaries going to legs, then they are going to drop off O2 in the tissues of the legs to the cells(internal respiration)
  - - - inflammation of nasal mucosa. if the mucosa spreads enough it can get to sinuses and cause Sinusitis(inflamed sinuses)
      - Larygitis
        
        inflammation of vocal cords. caused by viral infections
        
        Pleurisy
        
        inflammation of pleurae. pleurae become rough, causing friction and make stab like pain with every breath.
  - - - equals to 760 mm Hg (total atmospheric pressure)
    - - the partial pressure of each gas at equilibrium is the same in the liquid as in the gas.
  - - - 3 lobes
      - left
        
        2 lobes, cardiac notch
    - - apex at top
  - - - only external portion of the system
      - Nasal cavity
        
        mucus secreting cells.
        
        ciliated cells
        
        watery fluid containing enzymes
        
        paranasal sinues
        
        nasal conche
        
        superior, middle, inferior conche
        
        increase mucosal area, enhance air turbulence, filter, heat, and moisten air
        
        Pharynx
        
        nasopharynx
        
        houses pharyngeal tonsils
        
        oropharynx
        
        houses palatine and lingual tonsils
        
        laryngopharynx
        
        Lower respiratory (2 zones)
        
        conducting zone
        
        cleanses, warms, and humidifies air(larynx,trachea,bronchi)
        
        respiratory zone
        
        site of gas exchange (respiratory bronchioles, alveolar ducts, and alveoli)
        
        Larynx
        
        voice box
        
        provide patent airway
        
        routes air and food into proper channels
        
        vocal folds
