Question

air passages are lined by simple columnar epithelium. why?

Answer 1

Most of the respiratory passageways, from the nasal cavity through the bronchi, are lined by ciliated, pseudostratified columnar epithelium with goblet cells. Bronchioles are lined by simple cuboidal epithelium. (Lung alveoli, in contrast, are lined by very thin simple squamous epithelium.)
