Function: Simple Squamos
allows passage of materials by diffusion abd filtration in sites where protection is not important; secretes lubricating substances in serosae
Location: Simple Squamos
kidney glomeruli, air scas of lungs, blood vessels, and lymphatic vessels; lining of ventral body cavity (serosae)
Location: Simple Cuboidal
kidney tubules; ducts and secretory portions of small glands; ovary surface.
Function: Simple Columnar
absorption; secretion of mucus, enzymes, and other substances; ciliated type propels mucus or reproductive cells by cilliary action
Location: Simple Columnar
nonciliated type lines most of the digestive tract (stomach to anal canal), gallbladder, and excretory ducts of some glands; ciliated lines small bronchi, uterine tubes, and some regions of the uterus.
Function: Psuedostratified Columnar
secretion, particularly of mucus; propulsion of mucus by ciliary action
Location: Psuedostratified Columnar
nonciliated type in male's sperm-carrying ducts and ducts of large glands; ciliated variety lines the trachea. most of the upper respiratory tract
Location: Stratified Squamos
Nonkeratinized type forms the moist linings of the vagina, esophagus, and mouth; keratinzed variety forms the dry membrane
Location: Stratified Columnar
Rare in the body; small amounts in male urethra and in large ducts of some glands.
