Across
- 5. muscular tube posterior to nasal and oral cavities (swallowing refelexes)
- 6. muscle that helps with respiration by contraction when inhaling
- 8. skeletal structure that protects the heart and lungs
- 9. lubricates the pleural surface and makes it easy for them to slide over each other during lung inflation and deflation
- 12. protected by rib cage, pleural membrane, and serous fluid
- 13. the sum of two or more volumes (lung capacity)
- 14. tiny air sacs made of simple squamous tissue where oxygen and carbon dioxide exchange occurs
- 16. mucous membranes with epithelial tissue with goblet cells that produce mucous to trap bacteria and debris
- 18. this structure blocks dust and debris from entering
- 19. speaking and air passages
- 20. smallest branches of the 'bronchial tree' inside the lungs; lacks cartilage support
- 21. constriction of bronchioles , usually caused by allergens
- 22. opening of the larynx
- 23. destroy pathogens that did not get caught by mucous
- 24. warms and humidifies air that is breathed in
Down
- 1. frequent in newborns who have not produced the surfactant that reduces the surface tension of the fluid in the lungs
- 2. total air lungs can hold
- 3. structural features that supports the trachea to keep it open for air passage
- 4. inflammation of the lining of bronchial tubes, which carry air to and from the lungs
- 5. membrane that surrounds heart
- 7. covers the inside surface of the rib cage and spreads over the lungs as well
- 10. flap on top of larynx that folds down to prevent food and liquid entry
- 11. thin folds of tissue that are pulled over the glottis and vibrate during speech
- 15. amount of air in one breath
- 17. air that remains in the lungs after the most forceful exhale
- 25. a condition in which the air sacs of the lungs are damaged and enlarged, causing breathlessness
