  8. Simple Squamous Epithelium
    1) What is it made up of?
    2) What does it do/ line?
    • 1) a single layer of thin, flattened cells
    • 2) functions in exchange of gases in lungs and lines blood and lymph vessels as well as body cavities
  9. Simple Columnar Epithelium?
    1) What is it made up of?
    2) What does it line/ do?
    3) In the __, these cells posses __ that do what?
    4) __ can be found among columnar cells.
    • row of elongated cells whose nuclei are all located near the basement membrane
    • 2) line sthe uterus, stomach and intestines where it protects underlying tissues, secretes digestive fluids and absorbs nutrients
    • 3) intestine/ microvilli/ increase the surface area available for absorption
    • 4) mucus-secreting goblet cells
  10. Simple Cuboidal Epithelium?
    1) What is it made of?
    2) What is its function?
    • 1) consists of a single layer of cube-shaped cells with centrally located nuclei
    • 20 functions in secretion and absorption in the kidneys and in secretion in glands

    2) __ may be present, along with __, that do what?
    3) In the __, __ on thse cells aid in __ through the __ to the __.
    • 1) these cells appear layered due to the varying position sof their nuclei within the row of cells, but are not truly layered
    • 2) cilia/ mucus-secreting goblet cells/ line and sweep debris from respiratory tubes
    • 3) female reproductive tract/ cilia/ moiving eggs/ oviducts/ uterus
  12. Straitified Squamous Epithelium
