- 4. if this is reduced it is difficult to exhale
- 6. this increases with increased temperature
- 9. these nasal structures will warm and moisten air
- 11. part of brain that controls respiratory center
- 12. the rate in which you will breathe with increased CO2
- 14. thin cell for rapid diffusion of air
- 17. condition which causes resistance to airflow
- 18. this condition will make you breathe faster
- 19. structures for immunity but can be removed
- 21. structure that prevents food from entering lung

Down
- 1. can pass through the pharynx
- 3. white blood cell that carries bad particles
- 5. tiny hairs that line the respiratory tract
- 6. if you can control breathing during singing
- 7. this will make you breathe faster
- 8. sticky liquid that can capture particles
- 10. this increases when volume decreases
- 13. gas that controls rate/depth of breathing
- 15. flow of air when pressure increases in the lungs
- 16. prevents alveoli from collapsing
- 20. flow of air when chest increases and pressure increases
- 22. nerve that controls the diaphragm
