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