Bronchiole, Low Power
Description:This is a lower power picture of a bronchiole. Notice the lack of cartilage pieces in the adventitia. If they were present, you will be able to see them even at this magnification. The muscularis mucosae can be easily made out. Part of the mucosa is thrown into little folds. Look at these "lumps" carefully. Check the thickness of the wall of this conducting passage associated with these folds and you know that you are not dealing with a respiratory bronchiole (although at first glance there may be some resemblance).
