Respiratory System by Matthew Weiner
Across
- 4. the exhalation and expelling out respiratory waste products like carbon dioxide
- 7. a collection of organs whose main job is to take in oxygen and expel carbon dioxide
- 9. tissue that surrounds the lung
- 12. a very flexible piece of elastic cartilage that covers the opening of the trachea
- 14. the area of the throat that contains the vocal cords and produces vocal sounds
- 16. an inflammation and infection of the lungs
- 19. Bronchioles narrow and person may have difficulty breathing. (attacks can be triggered by dust, pollen, etc.)

- 10. shorter, broader, and is divided into three lobes
- 11. Airway that extends from the bronchus
- 13. breathing and cellular respiration
- 15. the exchange of oxygen and carbon dioxide between living cells and their environment;
- 17. tiny air sacs of the lungs where oxygen and carbon dioxide are exchanged
- 18. the tube that connects the larynx to the lungs
- 20. used to measure respiratory volumes and capacities
- 23. two external openings in the nasal cavity admits air to the lungs filtration of the air moisturization of the air
- 24. the passage from the mouth to the larynx and esophagus
