    Slide 108: Lung with pulmonary embolus
    There are several pieces of tissue on the slide. The one with the pulmonary embolus should be obvious.  The hole in the middle of the clot is an artifact of sectioning.  It was in fact solid but partially chipped out when it was sectioned.

    See this slide with the virtual microscope.

    There is nothing real fancy in this slide. It is a pulmonary embolus. Be sure you know the difference between a thrombus and an embolus, as well as the sorts of things that can potentially embolize. For that matter, be sure you know the factors that contribute to the formation of a thrombus. Remember there are  differences in formation on the venous and arterial sides of the circulation. Here's an interesting problem I almost always ask about on the written exams: paradoxical embolization . Know what it is?
