Airflow through the respiratory tract
Across
- 3. volume of lungs that is always present, even after full expiration
- 5. method of air transfer that occurs in alveoli, occurs over short distances
- 9. regions of bronchi with smaller diameters
- 11. substance produced by the respiratory epithelium
- 12. type of airflow in which resistance is higher
- 14. uppermost region of the lower respiratory tract, consists of lots of cartilage
- 15. contains the vocal chords
- 16. cavity through which air enters and turbulent flow occurs
- 20. respiratory muscle controlled by the phrenic nerve
Down
- 1. site of gas exchange
- 2. law that states that pressure and volume are inversely related to each other
- 4. lung parameters that depend on time
- 6. hair-like structures on surface of epithelium that function to trap pathogens and prevent them from entering the respiratory tract
- 7. branches that trachea split off into
- 8. volume of air we normally breathe in and out, without force
- 10. type of muscles that lines most of the respiratory tract
- 13. oral and nasal cavities combine here, allows food and air to pass
- 17. more controlled type of airflow
- 18. respiratory condition in which bronchioles constrict, often solved with an albuterol inhaler
- 19. lung parameters that do not depend on time, are unchanged
