Function: conduit for air and its conditioning.

MUCOSA

Composition:

Cells:

Function: provide a coordinated sweeping motion of the mucus coat -"ciliary escalator" - that serves as an important protective mechanism for removing small inhaled particles

Function: unicellular mucin-secreting glands

Function: receptor cells of general sensation

Function: release polypeptide hormones and/or catecholamines that are thought to function in reflexes regulating the airway or vascular caliber

Function: serve as a reserve population by maintaining individual cell replacement in the epithelium

Function: conditioning (warming, moistening and removal of particulate materials) of the air, prevention the epithelium from dehydration by moving air

Composition: loose connective tissue containing numerous lymphocytes, lymphatic tissue in diffuse and nodular forms

SUBMUCOSA

Composition: loose connective tissue with abundant blood and lymphatic vessels, diffuse lymphatic tissue and lymphatic nodules, mucus-secreting glands

CARTILAGINOUS LAYER

Function: provide flexibility to the tracheal pipe and maintain patency of the lumen.

Composition:

ADVENTITIA

Function: binds the trachea to adjacent structures.

Composition: loose connective tissue with large blood and lymphatic vessels, and nerves
