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 vessels are part of a venous plexus that provide heat-exchange to help condition air passing through the trachea.
Incomplete rings of hyaline cartilage encircle the trachea.
