Identify types of epithelium/function/location Flashcards
Simple columnar epithelium
Function: Absorption; secretion of mucus, enzymes, and other substances; ciliated type propels mucus (or reproductive cells) by ciliated action.
Location: nonciliated type lines most of the digestive tract (stomach to anal canal), gallbladder and excretory ducts of some glands; ciliated variety lines small bronchi, uterine tubes, and some regions of the uterus.
Simple squamous epithelium
Function: Allows passage of materials by diffusion and filtration in sites where protection is not important; secretes lubricating substances in serosae.
Location: Kidney glomeruli, air sacs of lungs, lining of heart, blood vessels, and lymphatic vessels; lining of ventral body cavity(serosae)
Stratified cuboidal epithelium
Function: protection
Location: Largest ducts of sweat glands, mammary glands, and salivary glands.
Stratified columnar epithelium
Function: protection and secretion
Location: rare in the body; small amounts in male urethra and in large ducts of some glands
Transitional epithelium
Function: stretches readily and permits distension of urinary organ by contained urine
Location: lines the ureters, urinary bladder, and part of the urethra
Stratified squamous epithelium
Function: protects underlying tissues in areas subject to abrasion
Location: nonkeratinized type forms the moist lining of the esophagus, mouth, and vagina; keratinized type forms the epidermis of the skin, a dry membrane.
Simple cuboidal epithelium
Function: secretion and absorption
Location: Kidney tubules; ducts and secretory portions of small glands, ovary surface.
Pseudostratified epithelium
Function: Secretion, particularly of mucus; propulsion of mucus bu ciliary action.
Location: nonciliated type in male’s sperm-carrying ducts and ducts of large glands; ciliated variety lines the trachea, most of the upper respiratory tract.
