    Type: Picture Slide
    Content: Includes four photos depicting the bronchioli and alveoli showing particle deposits, an x-ray of affected lungs, an illustration of affected lungs, and an enlargement of diseased lung tissue.

    Speaker Notes: The finer dust particles, those smaller than ten micrometers, are inhaled along with a breath of air and are carried into the lungs. Some of the particles are deposited into the lungs. Some of the particles are deposited in the bronchioli and alveoli; the rest are carried back out of the lungs during exhalation.
