  10. Simple epithelial tissue are found are found in areas with what kind of wear and tear?
    Lowest wear and tear
  11. Squamous Simple Epithelial Tissue
    Layer / Shape:
    Locations:
    Functions:
    • Layer / Shape:
    • Single layer of Flat Cells

    • Locations:
    • Air sacs of lungs (alveoli)
    • Glomerular capsule of the kidney
    • Endothelium of Heart
    • Blood vessels and Lymph vessel

    • Functions:
    • Filtration and Absorption
  12. Cuboidal Simple Epithelial Tissue
    Layers / Shape:
    Locations:
    Functions:
    • Layers / Shape:
    • Single layer of cube shaped cells

    • Locations:
    • Surfaces of the ovaries
    • Tubules of the kidneys

    • Functions:
    • Secretion & Absorption
  13. Coloumnal Simple Epithelial Tissue
    2 Kinds:

    Location:
    Function:
    • 2 Kinds:
    • Ciliated and Non-Ciliated

    • Layers / Shape:
    • Single Layer of rectangular shaped cells

    • Locations:
    • Ciliated - upper respiratory track, fallopian tubes and ducts of the testies

    Non-Ciliated - Stomach, small & large intestines, gall bladder, and digestive glands

    • Functions:
    • Ciliated -Moves mucus
    • Non-Ciliated - secretion and absorbtion
  14. Where are "stratified epithelial" tissues found?
    Areas of maximum wear and tear

    2 Kinds:
    Layers / Shape:
    Locations:
    Functions:
    • 2 Kinds:
    • Non-Keratinized and Keratinized

    • Layers / Shape:
    • Many Layers and Flat shaped cells

    • Locations:
    • Non-Keratinized - Wet Surfaces of the body (mouth and esophagus
    • Keratinized - (has Kerotin protein) - Forms outter layer of skin

    • Functions:
    • Non-Keratinized - Protect underlying structures
    • Keratinized - Waterproofing of skin, resistance to friction, impervious to bacteria
  16. Cubiodal Stratified Epithelial Tissue
