Across
- 5. the entire process of gas exchange between the atmosphere and cells
- 7. also called the windpipe and it extends down and splits into left and right bronchi
- 10. deficiency of O2 in the blood
- 13. this divides the nasal cavity into right and left parts and is composed of bone and cartilage
- 14. along with the epiglottis,prevents foreign objects from entering trachea and it also houses the vocal cords
- 17. exhalation
- 18. also called the throat and it is a passageway for air and food and it also helps produce the sounds of speech
- 19. soft, spongy, cone-shaped organs in the thoraciccavity
- 20. air sacs that are the site of gas exchange from the capillaries
- 22. groups of neurons that extend throughout the medulla oblongata
- 24. carbon dioxide transport mechanism
- 25. this is the potential space between visceral and parietal pleurae that has a thin film of serous fluid that lubricates the pleural surfaces
Down
- 1. groups of neurons in the brainstem that control both inspiration and expiration
- 2. the vital capacity plus the residual volume
- 3. deep and rapid breathing that lowers blood CO2 levels
- 4. enters into their respective lungs (left and right) (singular term is bronchus)
- 6. amount of pressure each gas (oxygen, CO2, nitrogen) contributes
- 8. the amount of air that remains in the lungs
- 9. force created by the attraction of water molecules
- 11. oxygen that has dissolved and combined with
- 12. these are air-filled spaces that reduce the weight of the skull and are resonant chambers that affect the quality of the voice
- 15. the amount of air inhaled, exhaled and stored within the lungs at any given time
- 16. inhalation
- 21. mixture of lipids and proteins that are secreted into alveolar spaces to reduce the alveoli’s tendency to collapse; it also makes it easier for inspiratory efforts to expand the alveoli
- 23. the maximum volume of air a person can exhale after taking the deepest breath as possible
