Across
- 1. Maximum volume of air we can expire below tidal volume.
- 6. These intercostal muscles are involved in expiration.
- 8. Small hair-like projections that push mucus towards the pharynx.
- 10. Law that states pressure is proportional to temperature.
- 11. A part of the upper respiratory tract that contains three pairs of tonsils.
- 13. Disorganized air that moves in all directions.
- 14. Amount of air that can be breathed in after maximal expiration.
- 17. Volume of air inspired and expired during normal breathing.
- 19. Law that states volume is proportional to temperature when pressure remains constant.
- 20. These muscles only contract during forced expiration.
Down
- 2. These intercostal muscles are involved in inspiration.
- 3. A part of the lower respiratory tract thatenter the lung from the trachea.
- 4. Small buds at the end of the respiratory tract where lots of gas exchange occurs.
- 5. Law that states pressure is inversely proportional to volume.
- 7. Contraction of this muscle causes it to flatten.
- 9. Organized air moving in the same direction.
- 12. Maximum volume of air we can inspire above tidal volume.
- 15. Total amount of air that can be filled in the lungs
- 16. Air moves through the respiratory system as a result of this gradient.
- 18. Volume of air remaining in lungs after complete expiration.
