quiz #1 pulmonary responses to exercise

  1. Respiratory System Functions include:




    E) All of the above

    (Speech- control of air thru larynx is another function)
  2. What percent of oxygen is in the air?
    21%
  3. Acute exercise:


    B) Increases Tidal Volume
  4. The bigger you are:


    C) The larger your TV
  5. The major muscle used during inspiration is:
    Diaphragm

    (the other inspiration muscles include the external intercostals and the accessory muscles)
  6. Ventilation=
    mechanical movement of air in and out lungs (ventilatory pump)

    (paralysis after a stroke would be a problem for ventilation)
  7. Diffusion (Respiration)=
    gas exchange from alveolus to capillary

    (problems with this include: ephysema, pneumonia, drownng person with water in lungs, and cystic fibrosis)
  8. Circulation=
    movement of blood from heart to body and back

    (problem: heart failure)
  9. O2 delivery=
    movement of oxygen from blood to tissues (working muscles)

    (problem: sickle cell)
  10. Expiration is:



    D) All of the above
  11. After exercise, the IRV (Inspiratory Reserve Volume) becomes


    A) less

    (because you breathe more)
  12. At rest your IRV is



    A) Between 2.5-3.5L
  13. Inspiratory Reserve Volume (IRV) is
    The max inspiration after tidal inspiration
  14. Expiratory Reserve Volume (ERV) is
    max expiration after tidal expiration
  15. At rest your ERV is



    D) Between 1.0-1.5L
  16. Residual Volume (RV) is
    Volume in lungs after max expiration
  17. With Acute Exercise:


    A) no change
  18. Aging and Disease does what to RV?


    C) Increases
  19. RV is a little larger in:


    B) Men
  20. Emphysema causes what shaped chest?
    barrel (because they have larger residual volume)
  21. Aging and disease does what to VC (Vital Capacity)?


    B) Decreases
  22. At rest the VC for males is 4-5L, what is is for women?


    B) 3-4L
  23. VC (vital capacity) is:
    Maximum can exhale after maximal inhalation

    • and
    • (IRV+ERV+TV)
  24. TLC (Total Lung Capacity) is:
    Total lung volume

    • and
    • (IRV+TV+ERV+RV)
  25. Inspiratory Capacity is:
    Max inspired after tidal expiration

    • and
    • (IRV+TV)
  26. Functional Residual Capacity is:
    Volume in lungs after tidal expiration

    • and
    • (ERV+RV)
  27. FVC (Forced Vital Capacity) is:
    Forced Expiratory Volume at 1sec
  28. FEV1/FVC reflects?
    expiratory power and resistance to air movement
  29. What are some effects of aerobic training on the pulmonary system?
    • ^ RBCS
    • ^ blood volume
    • decreased hematocrit
  30. What is hypoxemia?
    impaired ventilation perfusion ratio during high intensity exercise
