Describe the general characteristics of epithelial tissue. List the most important functions of epithelial tissues, and give examples of each. How are the structures of the different types of epithelial cells related to their functions? The general characteristics of epithelial tissue include interconnected cells act as a functional unit. The epithelial tissue can be organized into layers. It covers body surfaces and line lumen of organs. Epithelial tissue controls movement of materials between luminal and adlumenal. The final charachetistic of epithelial tissue is tight cell-to-cell junctions, morphological classifications consider shape and number of layers. The simple cuboidal secretes and absorbs (i.e. kidney tubules, small ducts)

Unformatted text preview: The double layers of cuboidal cells are for luminal wall support. Simple columnar secretes mucous and enzymes and serves in absorption (i.e. G.I tract lining) The Stratified columnar protects and secretes (i.e. male urethra and large ducts) The Simple ciliated columnar uses ciliary motion for facilitating transport (i.e. uterine tubes) The psuedostratified columnar is ciliated and help in secreting and moving mucous (i.e. trachea). The Simple squamous allows transport via diffusion (i.e. respiratory alveoli). The stratified squamous cells serve as a protective layer against abrasion....
