The cilia are always moving, bacteria or particles of dust trapped in the mucus are moved away by cilia.
The cilia waft the mucus containing bacteria and dust up to the back of the throat, so that it doesn't block up the trachea and thus keeps it clean.
Pseudostratified ciliated columnar with Goblet Cells
pseudostratified ciliated columnar epithelium cells with goblet cells that produce mucus!
The Trachea is lined with simple columnar ciliated epithelia. the cilia acts like a one way brush that moves the mucous containing dust etc. to the oesophagus and out of the airways.
lining the what?
The trachea carries air from the larynx to the lungs. The trachea is a tube that leads to two smaller tubes called bronchi See http://en.wikipedia.org/wiki/Hemoglobin
The trachea.
nostrils or oral cavity > nasal cavity > pharynx > epiglotis > larynx ( the voice box ) > trachea (windpipe) > bronchi > bronchioles > alveoli > blood > cells
Mucus secreted by goblet cells trap the foreign particles. Cilia push the particles out wards. This protects your lungs from damage by the foreign particles.
i dont even know what a mucosa line in the trachea is
Pseudostratified columnar cells line the inside of the trachea and simple squamous cells make up the alveoli
In the lumen of the trachea, this is the area that is in contact with the air coming in.Cilia are projections on the end of columnar epithelial cells that line the trachea (windpipe), they are responsible for beating (in a 'waving' motion) mucus filled with debris up the trachea out of the lungs and to the epiglottis where it can be swallowed and broken down safely in the stomach.
The trachea is lined with a moist mucous-membrane layer made up of cells containing small hairs called cilia. The cilia project into the channel (lumen) of the trachea to trap particles. There are also cells and ducts in the mucous-membrane that secrete mucus droplets and water molecules.Cilia are whiplike, motile cellular extensions that occur, typically in large numbers, on exposed surfaces of certain cells. In the trachea, ciliated cells that line the respiratory tract propel mucus laden with dust particle and bacteria upward away from the lungs. Centrioles, referred to as basal bodies, are the originating source of cilia.
Smoker's cough results from damage of the cells that line the trachea which have cilia. The cilia are damaged so that the mucus cannot be moved and therefore be swallowed. Coughing helps to remove the mucus. Also smoke irritates the cells of the trachea and produce the cough

Trachea's inner lining(lining that faces the hollow side) is comprised of ciliated epithelium which rests on a basement membrane made of protein fibers. In between the ciliates cells the goblet cells are situated. Beneath the epithelium is an area of loos tissue and tracheal glands that secrets mucus (both tracheal glands and goblet cells secrets mucus so don't get confused which one produces mucus). There is a C-Shaped cartilage in outer lining that supports the trachea.
