Anatomy CH. 25

  1. Function of the resp. tract
    • Allow for exchange of gases
    • Sensation of the olfactory stimuli
    • Sound Production
    • Immune Functions
  2. Upper resp. tract
    lined with pseudostratified columnar ciliated epithilia

    • Structures
    • 1. Nose 2. Nasal Cavity
    • 3. Sinuses 4. Pharynx
  3. Lower resp. tract
    Lined with various types of epithilia

    • Structures
    • 1. Larynx 3.Bronchi
    • 2. Trachea 4. Bronchioles
    • 5. Alveoli
