Trachea

The trachea is lined by ciliated, pseudostratified columnar epithelium.  For a closeup of this respiratory epithelium, click here.

This epithelium rests upon ordinary connective tissue which may include prominent blood vessels.  These are part of a venous plexus that provides heat-exchange to help condition air as it passes along the trachea.

Incomplete rings of hyaline cartilage encircle the trachea.
