They move 'mucus' and are cells that make up a 'mucous' membrane. Mucus is a noun, the thing that is secreted, and mucous is an adjective describing the quality of the thing that makes the mucus.
Mucous, made by mucous glands, stick to the cilia of cells that are found in the mucous membranes.
The nasal mucous membrane lines the nasal cavities.

Cigarette smoke irritates cells in the bronchi and this irritation triggers special cells to produce a layer of mucus designed to trap the foreign particles irritating the cells. This layer of mucus is then suppose to be swept away by the Cilia, though the tar found in cigarette smoke slows the action of the cilia. This tar accumulates in the mucus layer, because the cilia are not able to respond due to the presence of this tar. In conclusion, the mucus layer will gradually grow over time because the cilia will not be able to sweep away the accumulated foreign particles.
cilia
Cilia push the contaminated mucus out ward. so as to protect your lungs from damage.
Cilia
primary bronchi
In the lining of the trachea, bronchi, and bronchioles.
cilia
Mucous membranes and cilia in the trachea trap and eliminate particulate matter from inhaled air. The membranes also warm and moisten incoming air.
The bronchi are located in the lungs and are coated with mucus. They also have cilia which are small hair-like projections on the surface of the bronchi that move the mucus towards the outside of the body.
