Bronchus to bronchiole transition
The smallest bronchi transition to bronchioles. Bronchioles differ from bronchi in that they lack glands and cartilage plates. As they decrease in size, the ciliated epithelium changes from pseudostratified to columnar to cuboidal and goblet cell numbers are reduced. Like bronchi, bronchioles are intrapulmonary, conducting passageways. 100x
