Histological section of the trachea stained with H&E, showing the layered structure of the airway wall. The mucosa is lined by pseudostratified ciliated columnar epithelium with goblet cells, basal cells, and a distinct basement membrane, highlighted in an inset. Beneath the lamina propria lies the submucosa containing seromucous glands, shown in a separate inset. The tracheal wall includes hyaline cartilage rings and the trachealis muscle posteriorly, with adventitia forming the outer layer. The image illustrates the organization of the trachea and its specialized respiratory epithelium.
