Across
  1. 4. assessment method that measure volumes of air moved during inspiration and expiration
  2. 7. amount of air that can be forcefully exhaled after a maximum inhalation
  3. 9. characterized by the accumulation of fibrous connective tissue, occurs due to the constant inhalation of particles less than 6 um
  4. 10. volume of gas remaining in the lungs after a maximum expiration
  5. 12. type of membranous structure lining thoracic (and other) cavity
  6. 14. air in conducting zone where no gas exchange occurs
  7. 17. has large surface area, place of diffusion of gases
  8. 18. amount of air expired/breath in quiet breathing
  9. 20. another name for inhalation
  10. 21. substance made of phospholipids that is secreted by type II cells on the surface of alveoli reducing the surface tension
Down
  1. 1. results from pressure differences as air moves from higher to lower pressure
  2. 2. the maximum volume of gas that can be expired during forceful breathing in addition to tidal volume, is approximately 1L
  3. 3. cavity created by the presence of the diaphragm
  4. 5. thin fluid layer between visceral and parietal pleura
  5. 6. the maximum volume of gas that can be inspired during forceful breathing in addition to tidal volume, is approximately 3L
  6. 8. type of membranous structure covering lungs (and other organs)
  7. 11. diaphragm contracts, use of parasternal and external intercostal muscle contraction
  8. 13. diaphragm relaxes
  9. 15. results from episodes of obstruction of air flow through bronchioles
  10. 16. another name for exhalation
  11. 19. movement of air from higher to lower pressure
