Across
  1. 1. allowing oxygen to diffuse into the blood and carbon dioxide to exit the body, crucial for respiration
  2. 4. produces pleural fluid, reduces friction, enables lung expansion via suction, and contains pain nerves
  3. 7. reducing friction during breathing
  4. 9. carries deoxygenated (oxygen-poor) blood from the right ventricle of the heart to the lungs for oxygenation
  5. 13. main airway, facilitating the passage of air between the larynx and the bronchi
  6. 14. conducts air between the trachea and the left lung
  7. 17. facilitating breathing
  8. 21. approximately 15% to 20% of total lung function
  9. 23. transport oxygenated blood from the lungs to the left atrium of the heart
  10. 24. contributes approximately 10% to total lung capacity, playing a vital role in gas exchange (oxygenation and carbon dioxide removal).
  11. 26. minimizes friction during breathing, allows smooth lung movement, and maintains negative pressure to keep the lungs expanded
  12. 29. exchange oxygen and carbon dioxide during respiration
  13. 30. the smallest compartment of the thoracic cavity, located between the sternum anteriorly and the pericardium posteriorly
  14. 31. They allow for collateral airflow to ensure gas exchange, balance surface tension, and facilitate the movement of macrophages and surfactant
Down
  1. 2. The primary site for gas exchange
  2. 3. protect vital thoracic organs (heart, lungs, great vessels) and upper abdominal viscera, provide structural support for breathing
  3. 5. They are crucial for breathing and maintaining blood oxygen levels
  4. 6. reducing friction during beats, anchoring the heart within the chest, preventing overfilling/dilation of chambers, and acting as a physical barrier against infection
  5. 8. transports food, liquids, and saliva from the pharynx to the stomach
  6. 10. function to conduct air, produce surfactant, and detoxify toxins. They are crucial sites for epithelial repair
  7. 11. Featuring scattered alveoli in their walls, they connect conducting airways to gas-exchanging alveoli, allowing limited gas exchange.
  8. 12. produces and matures T-lymphocytes (T-cells)
  9. 15. they serve as crucial passages for air distribution and facilitate gas exchange by allowing oxygen to enter and carbon dioxide to exit the alveoli
  10. 16. act as the conduit for airways (bronchi), vessels (pulmonary/bronchial), nerves, and lymphatics to enter/exit the lungs, while also anchoring the lungs to the mediastinum
  11. 18. the major vessel originating from the right ventricle that carries deoxygenated blood to the lungs
  12. 19. essential for breathing by controlling rib cage movement
  13. 20. independent expansion and movement of the lobes during respiration.
  14. 22. divide the lung into distinct anatomical lobes, allowing them to move independently, reducing friction, and localizing diseases, while providing structural landmarks for imaging
  15. 25. drives breathing by contracting and flattening to inhale (creating a vacuum) and relaxing to exhale
  16. 27. critical for gas exchange, air filtration, and, notably, is often the first site for specific infections like tuberculosis due to these unique pressures.
  17. 28. acts as a critical, protective, and structural component of the human body. It acts as a shield for the heart, lungs, and major blood vessels while connecting the ribs and collarbones to form a stable cage
