Mae Stansbury, Period 5, Respiratory System - Coggle Diagram

- - - - Scroll like mucosa-covered projections that protrude medially from each lateral wall of nasal cavity
      - Helps to increase mucosal area
      - Enhances air turbulence
      - Filters, heats, and moistens air
  - - - Nasopharynx
        
        air passageway
        
        posterior to nasal cavity
        
        soft palate and uvula close nasopharynx during swalling
        
        Pharyngeal tonsils are located in the posterior wall
      - Oropharynx
        
        passageway for food and air
        
        from level of soft palate to epiglottis
        
        palatine tonsils located in lateral walls of fauces
        
        Linguan tonsil located on posterior surface of tongue
      - Laryngopharynx
        
        passageway for food and air
        
        posterior to upright epiglottis
        
        extends to larynx and is continuous with esophagus
- - - - Mucosa: ciliated pseudo stratified epithelium with goblet cells
      - Submucosa: connective tissue with seromucous glands hat help produce the mucous sheets in trachea
      - Adventitia: outermost layer made of connective tissue
  - - - Conducting zone structures give rise to respiratory zone structures
      - Primary bronchi (right main bronchus wider, shorter, more vertical than left)
      - Secondary bronchi (3 on right, 2 on left, each lobar supplied one lobe
      - Tertiary bronchi (segmental bronchi divide repeatedly)
    - - Terminal bronchioles are smallest of all branches
  - - - separated into superior and inferior lobes by oblique fissure
      - smaller than right
    - - separated into superior, middle, and inferior lobes
      - superior and middle lobes are separated by horizontal fissure
      - Middle and inferior lobes are separated by oblique fissure
