Document Summary
Describe where epithelial tissue is found and its functions. Skin surface, can be found lining the digestive tract organs and other hollow organs. Forms boundaries between different environments, protects, secretes, absorbs, filters. Classify epithelia based on shape and number of layers. Know which part of an epithelial cell is connected to underlying connective tissue. Basal lamina: basement membrane; underlying connective tissue. Clear layer - contains glycoproteins & network of fine protein filaments. Dense layer - bundles of coarse protein fiber gives basal lamina strength. Simple cuboidal: kidney tubules, ducts and secretory portions of small glands; ovary surfaces. Transitional: lines the ureters, bladder, and part of the urethra. Simple columnar: nonciliated type lines most of the digestive tract (stomach to rectum), gallbladder, and excretory ducts of some glands; ciliated variety lines small bronchi, uterine tubes, and some regions of the uterus.
