Across
- 4. a progressive, genetic disease that causes persistent lung infections and limits the ability to breathe over time
- 6. inflammation of air passageways to the lungs
- 11. network of branches from the primary bronchi
- 13. something moves from an area of high concentration to one of low concentration
- 14. cause by reduced air pressure and lower oxygen concentration
- 16. ducts that connect the bronchioles to the alveoli sacs
- 19. bones that divide the nasal cavity, supports the mucas membrane, and increases surface area
- 20. opening that is surgically made through the neck to the trachea to allow direct access to a breathing tube
- 22. rebound of lungs that forces air out when the diaphragm relaxes
- 23. control breathing
- 25. obstruction of airways
Down
- 1. these do not produce vocal sounds, but they help close the airway after swallowing
- 2. space in the left lung where the heart resides
- 3. two branches emerging from the trachea
- 5. muscles between the ribs that expand and shrink when breathing
- 7. oxygen diffuses from the blood into the body's tissues
- 8. process of exchanging oxygen and carbon dioxide with an external environment
- 9. occurs when abnormal cells grow out of control in the lungs
- 10. membrane that covers the lungs
- 12. pause or slowing of breathing while sleeping
- 15. a tube reinforced by rings, extending from the larynx to the primary bronchi and transporting air to and from the lungs
- 17. houses vocal cords
- 18. bone that separates the nasal cavity into two
- 21. these create vocal sounds
- 24. sacs that enable gas exchange
