Ciliated pseudostratified<br />

columnar epithelium with<br />

goblet cells<br />

Note the thick basement membrane of the respiratory<br />

pseudostratified columnar epithelium.<br />

The main function of<br />

cilia is to sweep or<br />

move fluids, cells, or<br />

particulate matter<br />

across cell surface<br />

in the lumen as to<br />

remove dust in the<br />

lungs. Microtubules<br />

of the axoneme are<br />

at the core of cilia<br />

and make them<br />

motile.
