    the part of pharynx below upper edge of epiglottis, opening into larynx and esophagus (hypopharynx)
  23. larynx
    musculocartilaginous structure at top of trachea and below root of tongue and hyoid bone, housing vocal chords (voice box)
  24. maxillary sinuses
    two air spaces in maxilla, communicating with middle opening of nasal cavity on each side
  25. mediastinum
    space in thorax between two pleural sacs, containing such structures as heart and blood vessels
  26. minimal volume
    air remaining in alveoli of collapsed lung
  27. mucous membrane
    epithelial lining of respiratory tract
  28. naris, nares
    nostril (s)
  29. nasal septum
    membranous, skeletal partition between nasal cavities
  30. nasopharynx
    the part of pharynx above soft palate of mouth, opening into nose
  31. obligate nasal breather
    able to breathe only through nasal passages (e.g., horses)
  32. oropharynx
    the part of pharynx between soft palate and upper edge of epiglottis
  33. oxygen (O2)
    element in air necessary for life, used by all cells of body
  34. parietal pleura
    lining of thoracic cavity
  35. pharynx
    airway between nasal chambers, mouth, and larynx; also passageway for food
  36. phrenic nerve
    nerve of diaphragm
  37. pleura
    serous membrane encasing lungs, lining thoracic cavity, and enclosing pleural cavity (potential space)
  38. pleural cavity
    potential space between parietal and visceral layers of pleura
  39. residual volume
    air remaining in lungs after forced expiration
  40. respiration
    process involving inspiration and expiration, distribution of oxygen to cells of body, and removal of carbon dioxide from these cells
  41. retropharynx
    back part of pharynx
  42. sphenoid sinuses
    spaces in sphenoid bone, opening to nasal cavity

  47. turbinates
    papery, scroll-like bones that support mucous membranes of nose
  48. vagus nerve
    nerve extending from brain to pharynx, larynx, and thoracic and abominal viscera (vagus means wandering)
  49. vestibule
    front part of nostrils and nasal cavity
  50. visceral pleura
