Across
- 2. Left lung does not have this
- 5. Directs air to the regions of the lung where gas exchange occurs
- 6. Produces pleural fluid that lubricates the pleural cavity, reducing friction during respiration
- 12. Maintains lung expansion during inhalation.
- 13. Provides a lubricated space between the lungs and chest wall for smooth movement during breathing
- 16. Connects the lungs to the mediastinum
- 17. Runs diagonally from the posterior to the anterior aspect of the lung
- 18. Inferior to the oblique fissure laterally adjacent to the heart
- 19. Delivers air to the alveoli
- 20. Separates the right lung into the upper, middle, and lower lobes
Down
- 1. Serves as a protective membrane covering the lungs
- 3. Provides a moist environment to help gases diffuse more easily
- 4. Acts as the primary muscle for breathing
- 7. Positioned anteriorly and laterally adjacent to the heart
- 8. Serves as the entry and exit point for major structures
- 9. Carries air to your lungs
- 10. Separates 6 down from the middle lobe of the right lung
- 11. Tiny air sacs where gas exchange occurs
- 14. Facilitate gas exchange by allowing air to flow between alveoli
- 15. Involved in respiration above 5 across
