- In order to cover and protect the more delicate cell layers underneath it and to trap waste and particle matter, including microorganisms, mucous membranes are made up of a layer of epithelial cells connected by tight junctions.
- Because they feature ciliated appendages, which resemble hairs, the epithelial cells lining the upper portions of the respiratory tract are known as ciliated epithelial cells.
- Mucus that contains debris is forced out and away from the lungs by the cilia's movement. The mucus is then coughed up, sneezed out, or swallowed and destroyed in the stomach. The mucociliary escalator is another name for this route of elimination.
