  13. 30. A flap of cartilage that covers the glottis during swallowing to prevent food or liquid from entering the trachea
  14. 31. A wall of cartilage and bone that divides the nasal cavity in half medially (2 Words)
  15. 33. serves as the primary entrance for air into the respiratory system; contains hair and mucous membranes that filter, warm, and moisten air
  16. 34. The space between the parietal and visceral pleura, filled with lubricating fluid to prevent friction during respiration (2 Words)
  17. 36. Hollow spaces in bones of the skull; reduce weight of the skull; serve as resonant chambers; spaces for conditioning of air
  18. 38. Rapid or deep breathing that reduces carbon dioxide levels in the blood, potentially causing dizziness or fainting
  19. 39. The perceived frequency of a sound, determined by the tension and length of the vocal cords
  20. 40. A ring-shaped cartilage located below the thyroid cartilage that provides support to the larynx (2 Words)
  21. 44. A chronic respiratory condition causing airway inflammation, constriction, and excess mucus production, leading to wheezing and shortness of breath
  22. 46. The movement of chloride ions into red blood cells as bicarbonate ions exit to maintain electrical balance during gas exchange (2 words)
  23. 47. The movement of gases (oxygen and carbon dioxide) across the alveolar and capillary membranes due to concentration gradients
  24. 48. Bands of tissue within the larynx that vibrate to produce sound when air passes through them (2 Words)
  25. 51. connects the nasal cavity and mouth to the larynx and esophagus
  26. 52. Openings of the nose that allow air to enter and exit the nasal cavity
  27. 53. A compound formed when carbon monoxide binds to hemoglobin, reducing oxygen transport in the blood
  28. 54. The lower section of the pharynx, connecting the oropharynx to the larynx and esophagus; directs air to the larynx and food to the esophagus
  29. 55. Muscles involved in breathing, including the diaphragm and intercostal muscles (2 Words)

  2. 2. A group of neurons in the brainstem (medulla oblongata and pons) that regulate breathing rate and depth (3 Words)
  3. 3. Tubes that connect the middle ear to the nasopharynx, helping to equalize air pressure on both sides of the eardrum (2 Words)
  4. 5. The blood vessels that carry oxygenated blood from the lungs to the left atrium of the heart (2 Words)
  5. 8. The process of exhaling air from the lungs, often a passive process due to lung recoil
  6. 9. Hollow space within the nose; conducts air to pharynx (2 Words)
  7. 12. The amount of air remaining in the lungs after a forceful exhalation, preventing lung collapse
