Across
  1. 4. This zone of the respiratory system contains the alveolar ducts.
  2. 7. These intercostal muscles are supplementary to inspiration.
  3. 9. This can be found by adding and individual's tidal volume with their inspiratory reserve volume.
  4. 12. Given a certain change in pressure, how difficult is it to cause a volume change?
  5. 13. The alveoli tend to experience this when trans-pulmonary pressure is negative.
  6. 14. Total volume of air that can be moved into or out of lungs.
  7. 16. Volume of air displacement during normal quiet breathing.
Down
  1. 1. These muscles are recruited during forced expiration.
  2. 2. Normally, this is occurs passively.
  3. 3. This is the pressure difference between the alveolar pressure and the inter-pleural pressure.
  4. 5. Allows small alveoli to have a lower inflating pressure.
  5. 6. The alveoli tend to experience this when trans-pulmonary pressure is positive.
  6. 8. This zone of the respiratory system contains the 20th generation bronchioles.
  7. 10. The nitrogen washout technique is used to determine this value.
  8. 11. This process requires shortening of the diaphragm.
  9. 15. This zone of the respiratory system consists of the nose and mouth.
