What is this?

Distinguishing airway regions by how their walls are built helps identify what’s shown. The image displays cartilage in the wall arranged as plates, a relatively thick mucosa with secretory glands, and an epithelium that is pseudostratified and ciliated with goblet cells. This combination is characteristic of a bronchus, a major conducting airway that maintains airway structure and helps clear mucus and debris. bronchioles would lack cartilage and glands and are lined by simple cuboidal or nonciliated epithelium with Clara cells. Alveoli are tiny air sacs with very thin, flat (simple squamous) lining and surrounding capillaries, with no cartilage. The trachea has distinctive C-shaped rings of cartilage rather than plate-like walls. So the features shown align with a bronchus.
