  19. tonsill/o
  20. trache/o
    trachea (windpipe)
  21. uvul/o
  22. nose
    structure that warms, moistens, and filters air as it enters the respiratory tract; also houses the olfactory receptors for the sense of smell
  23. sinuses
    air-filled spaces in the skull that open into the nasal cavity
  24. palate
    roof of the mouth; partition between the oral and nasal cavities; divided into the hard and soft palate
  25. hard palate
    bony anterior (front) portion of the palate
  26. soft palate
    muscular posterior (back) portion of the palate
  27. pharynx
    throat; passageway for food to the esophagus and for air to the larynx
  28. nasopharynx
    part of the pharynx directly behind the nasal passages
  29. oropharynx
    central portion of the pharynx between the roof of the mouth and the upper edge of the epiglottis
  30. laryngopharynx
    lower part of the pharynx, just below the oropharyngeal opening into the larynx and esophagus
  31. tonsils
    oval lymphatic tissues on each side of the pharynx that filter air to protect the body from bacterial invasion; also called palatine tonsils
  32. adenoid
    lymphatic tissue on the back of the pharynx behind the nose; also called pharyngeal tonsil
  33. uvula
    small projection hanging from the back middle edge of the soft palate; named for its grape-like shape
  34. larynx
    voice box; passageway for air moving from the pharynx to the trachea; contains the vocal cords
  35. glottis
    opening between the vocal cords in the larynx
  36. epiglottis
    a lid-like structure that covers the larynx during swallowing to prevent food from entering the airway
  37. trachea
    windpipe; passageway for air from the larynx to the area of the carina, where it splits into the right and left bronchi
  38. bronchial tree
    branched airways that lead from the trachea to the microscopic air sacs called alveoli
  39. right bronchus and left bronchus
    two primary airways branching from the area of the carina into the lungs
  40. bronchioles
    progressively smaller tubular branches of the airways
  41. alveoli
    thin-walled, microscopic air sacs that exchange gases
  42. lungs
    two spongy organs in the thoracic cavity enclosed by the diaphragm and rib cage; responsible for respiration
  43. lobes
    subdivisions of the lung, with two on the left and three on the right
  44. pleura
    membranes enclosing the lung (visceral pleura) and lining the thoracic cavity (parietal pleura)
  45. pleural cavity
    potential space between the visceral and parietal layers of the pleura
  46. diaphragm
    muscular partition that seperates the thoracic cavity from the abdominal cavity and that moves upward and downward to aid in respiration
  47. mediastinum
    partition that seperates the thorax into two compartments (containing the right and left lungs) and that encloses the heart, esophagus, trachea, and thymus gland
  48. mucous membranes
    thin sheets of tissue that line respiratory passages and secrete mucus, a viscid (sticky) fluid
  49. cilia
    hair-like processes from the surface of epithelial cells, such as those of the bronchi, to move mucous cell secretions upward
  50. parenchyma
    functional tissues of any organ, such as the tissues of the bronchioles, alveoli, ducts, and sacs, that perform respiration
