What is the trachea?
What is the function of the trachea?
The inner surface of the trachea is lined with a respiratory epithelium consisting of ciliated epithelial cells, brush cells and goblet cells. The goblet cells, together with glands, secrete a secretion that creates a mucus film on the surface that binds suspended particles and small inhaled particles. The hairs of the ciliated epithelial cells then carry this mucus up the pharynx.
Where is the trachea located?
What problems can the trachea cause?
The trachea can be acutely or chronically inflamed. Possible triggers of tracheitis include viruses, bacteria or irritant gases.
If you inhale a foreign body and it gets stuck in the trachea, a doctor must remove it with the help of a bronchoscope.
