Across
- 1. The middle lobe of the right lung contributes to gas exchange and occupies the medial portion of the right lung.
- 3. a tube that conducts air from the larynx to the bronchi, allowing passage of air into the lungs.
- 9. – the uppermost lobe of the right lung and is responsible for gas exchange in the upper right lung region.
- 10. Separates the right superior lobe from the right middle lobe, aiding in the division of lung function.
- 11. A thin membrane that covers the surface of the lungs and reduces friction during breathing.
- 13. The upper lobe of the left lung, also involved in gas exchange.
- 14. Tiny ducts leading from respiratory bronchioles to alveolar sacs, directing air to alveoli.
- 15. major muscle of respiration that contracts to expand the thoracic cavity, helping draw air into the lungs.
- 18. Separates the left superior and inferior lobes, allowing them to function independently.
- 20. Tiny air sacs where the primary gas exchange of oxygen and carbon dioxide occurs between air and blood.
- 21. The lower lobe of the left lung, responsible for oxygen and carbon dioxide exchange.
Down
- 2. Pumps oxygenated blood to the body and deoxygenated blood to the lungs for oxygenation.
- 4. The apex is the top portion of the lung.
- 5. Small branches of the bronchioles where some gas exchange begins to occur.
- 6. Small openings between alveoli that allow for pressure equalization and alternate air pathways.
- 7. The space between the visceral and parietal pleura that contains fluid to reduce friction during lung movement.
- 8. a lymphoid organ where T cells mature.
- 12. Divides the right middle lobe from the right inferior lobe,
- 16. The membrane that lines the chest wall and diaphragm, aiding in smooth lung expansion.
- 17. Muscles between the ribs that help expand and contract the chest cavity during breathing.
- 19. The bottom portion of the lung that rests on the diaphragm and functions in gas exchange.
