Question

What is the lining of the respiratory track made up of?

Answer 1

Explanation:

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.)

Answer 2

columnar epithelium

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.)
