    TEXT VERSION OF SLIDE:

    Title: Structure of the Lungs
    Type: Picture Slide
    Content: Illustration of air passage way and lungs of a person identifying the esophagus, trachea, pleura, bronchus, pulmonary artery, pulmonary vein and diaphragm. Also includes a blow-up illustration of the bronchus identifying the alveoli, bronchiole, pulmonary venule, pulmonary arteriole, and pulmonary artery.

    Speaker Notes: Almost any type of dust may become a hazard when it becomes airborne. Once inhaled into the lungs, small particles of the dust can become trapped in the small air passages and air sacs (called the alveoli). Usually, the dust particles must be very small -- less than five micrometers -- in order to travel this far.
