  34. oropharynx
    the oral cavity, which extends from the uvula to the epiglottis.
  35. parietal pleura
    the pleural membrane that lines the pleural cavity.

    **pleura that lines the inner chest wall and covers the diaphragm
  36. partial pressure of carbon dioxide (PaCO2)
    a measurement of the amount of carbon dioxide in the blood.
  37. partial pressure of oxygen (PaO2)
    a measurement of the amount of oxygen in the blood.
  38. pH
    the measure of acidity or alkalinity of a solution.
  39. pharynx
    the cavity formed by the posterior connection of the oropharynx and nasopharynx.
  40. pleura
    serous membranes surrounding the lungs.
  41. pleural cavity
    the cavity formed by the inner borders of the rib cage.

    **potential space between the visceral and parietal pleura
  42. pleural space -- a potential space between the visceral and
    a potential space between the visceral and parietal pleura
  43. primary respiratory acidosis
    decrease in the blood pH secondary to insufficient exhalation of CO2.
  44. primary respiratory alkalosis
    increase in the blood pH secondary to excessive exhalation of CO2.
  45. pulmonary function tests
    tests that assess volumes of air that move into and out of the lungs.
  46. residual volume
    the volume of air remaining in the respiratory passages and lungs after a forceful expiration

    structures formed by the final branching of the bronchioles.
  48. respiratory center
    the part of the brain located in the medulla oblongata that controls the respiratory stimulus.
  49. respiratory system
    the organs and structures associated with breathing, gas exchange, and the entrance of air into the body.
  50. restrictive lung disease
    diseases such as black lung disease and asbestosis that result in stiffening of the lungs and significantly decreased vital capacity.
