    Secretion and absorbtion
  2. Stratified epithelium mainly function to
    Provide proctection from mechanical or chemical stresses.
  3. Simple squamous epithelium is found in:
    • -mesothelia lining in ventral body cavities
    • -endothelia lining heart and blod vessels
    • -kidney tubules
    • -inner lining of cornea
    • -alveoli of lungs
  4. The inner ling of cornea, alveoli of lungs, portions of kidney tubules and mesothelia and endothelia linings are made up of which classification of epithelium?
    simple squamous epithelium
  5. Functions of simple squamous epithelium include:
    • -reduction of friction
    • -control of vessel permeability
    • -absorption and secretion
  6. Stratified squamous epithelium is located:
    • -surface of skin
    • -lining of mouth, throat and esophagus
