Respiratory mucosa
The mucosa of the majority of the conducting passageways (through the larger bronchioles) is lined by a pseudostratified columnar epithelium with cilia. A lamina propria consisting of loose connective tissue is located beneath the epithelium. Either a smooth muscle layer or an elastic lamina is frequently present in the lamina propria. 400x, 400x
