Vital Vocabulary Cards for Jones and Barlett AAOS Paramedic: Anatomy and Physiology
Show Answers:

  1. alveolar ducts
    ducts formed from division of the respiratory bronchioles in the lower airway; each duct ends in clusters known as alveoli.
  2. alveoli
    tiny sacs of lung tissue in which gas exchange takes place.
  3. alveolocapillary membrane

    a reversible restrictive lower airway disease.

    medication that is designed to improve lung function.
  11. bronchospasm
    constriction of the airway passages of the lungs that accompanies muscle spasms.
  12. carina
    the projection of the lowest portion of tracheal cartilage, at the level of the fifth thoracic vertebra.
  13. chronic bronchitis
    chronic inflammatory condition affecting the bronchi that is associated with excess mucus production that results from overgrowth of the mucous glands in the airways.
  14. chronic obstructive pulmonary disease (COPD)
    a progressive and irreversible disease of the airway marked by decreased inspiratory and expiratory capacity of the lungs.
  15. conchae
    three bony ridges contained within the lateral walls of the nasopharynx.
  16. diffusion
    the process by which a gas dissolves in a liquid.
  17. emphysema
    destruction of the walls of the alveoli, which creates resistance to expiratory airflow.
  18. epiglottis
    a thin plate of cartilage that closes over the glottic opening during swallowing.
  19. esophagus
    the tubular organ posterior to the trachea, connecting the pharynx to the stomach.
  20. external nares
    the external openings to the nasal cavity; also called the nostrils.
  21. forced expiratory vital capacity (FEVI)
    the volume of air exhaled from the lung following a forceful exhalation.
  22. glottis
    the opening into the lower airway made up of the true vocal cords and the opening between them
  23. hard palate
    the floor of the nasal cavity.
  24. hilum
    the point of entry for the bronchi, vessels, and nerves into each lung.
  25. interior nares
    the posterior opening from the nasopharynx into the pharynx.
  26. larynx
    the opening of the lower airway, which consists of several cartilaginous structures held together by ligaments.
  27. lingula
    a small portion of the left lung that is the equivalent of the middle lobe in the right lung.
  28. lungs
    the two primary organs of breathing.
  29. mainstem bronchi
    the part of the lower airway below the larynx through which air enters the lungs.
  30. meatus
    a passage located below each turbinate.
  31. nasal septum
    the separation between the right and left nostrils.
  32. nasolacrimal ducts the ducts that drain tears from the
    the ducts that drain tears from the lacrimal sacs to the meatus
  33. nasopharynx
    the nasal cavity, which extends from the internal nares to the uvula.
  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
  47. respiratory bronchioles
    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.
