Unlike simple because has more than one layer. Keratin-surface cells that are dead: gyno looks for ratio of keratin vs non keratin. Found in lining of the mouth: stratified cuboidal. Lines sweat gland ducts: stratified columnar. Lines large ducts of some adult glands: transitional. One shape, then changes to a different. Stretches for fluid (bladder: glands, endocrine.
