Bronchiole

This smaller bronchiole is still lined by a pseudostratified columnar epithelium with cilia. The contraction of the thick smooth muscle layer produced the folding typical of this passageway; this muscle reaches its greatest relative thickness in the bronchiole. No cartilage nor mixed glands are present. 100x
