The tracheal epithelium is thick and has the appearance of more than 1 layer of cells. The tracheal epithelium gives an optical illusion of being pseudostratified due to the nuclei of cells on different levels, thus making it look multi layered.
Pseudostratified epithelium is a normal part of the human body.
pseudostratified columnar epithelium
The cells that line the epithelium in the tracheae are ciliated pseudostratified columnar epithelium cells.They are of three types -ciliated cellsgoblet cellsbasal cells
Thats epithelium is thick, has composition is more than 1 layers cells. The Structure of that epithelium has a strike corelation with the function of trachea, to protect the trachea from any kind of bacteria, dust, foreign micro matters etc, for the keep airway is the best for our breathing, espescially to keep intake the oxigen and to keep out the carbon dioxide.

pseudostratified ciliated columnar epithelium
Pseudostratified columnar epithelium is an epithelial tissue comprised of only one layer of cells. The nuclei of these column shaped cells are located at varying levels which make it appear as though there are multiple layers.
