    Simple Squamous Epithelium

    • Structure: Single layer of flattened cells with disc shaped central nuclei and sparse cytoplasm.
    • Function: Allows passage of materials by diffusion and filtration.
    • Location: Kidney, air sacs of lungs, lining of heart, blood vessels and lymphatic vessels.

    Pseudostratified Columnar Epithelium Ciliated

    • Structure: Single layer of cells of differeing heights, some not reaching the free surface; nuclei seen at different levels; may contain goblet cells or have cilia.
    • Function: Secretion, particularly of mucus; propulsion of mucus by ciliary action.
    • Location: Ciliated types line the trachea, most of the upper respiratiory tract.
    • Non ciliated types line male's sperm carrying ducts.
