Across
- 4. The area of the throat used for speaking, breathing, and swallowing that houses the vocal cords.
- 7. gives large area for gas exchange,moves air to and from the gas-exchange surfaces of the lungs, protects respiratory surfaces
- 10. A large airway from the lung to the trachea (windpipe)
- 11. In each lung, the primary bronchi branch into smaller and smaller airways, forming the bronchial tree.
- 12. the throat, a chamber shared by the digestive respiratory systems.
- 13. reduces surface tension
Down
- 1. Maximum amount of air that can be moved in/out of the respiratory system through a single respiratory cycle
- 2. windpipe, tough, flexible tube
- 3. A narrow passage where the diameter of the passageway has narrowed to about 1 mm, cartilages disappear.
- 4. Each of the two lungs that are separated by deep fissures.
- 5. Sets the pace for respiration (3 pairs of nuclei in reticular formation).
- 6. Lined by a protective mucous membrane, or respiratory mucosa, making the nose moist by creating mucus
- 8. The exchange that takes place within the lungs at air-fileld pockets
- 9. consists of the squamous alveolar epithelium, endothelial cells, and fused basement membranes
- 12. The pressure contributed by a single gas is the partial pressure of that gas, abbreviated as P.
