    FUNCTION : Moves fluids and particles along passageways. LOCATION: Found in respiratory tract, fallopian tubes, sinuses.
  • What are Tight Junctions?
    A fluid tight seal between cells to prevent leaking of substances into blood or surrounding tissues; stomach lining & urinary bladder, and intestines.
  • what is endoderm?
    The lower germ layer that gives rise to the GI tract, urinary bladder, and respiratory tract.

    Function: Produce hormones LOCATION: Thyroid, pituitary Gland, ovaries, testicles
  • What is Gap Junction?
    Allows passage of chemical/ electrical signals through connexons from cell to cell; muscular contraction, pain.
  • what are cell junctions?
    A point of contact between adjacent membranes of various cell types.
  • what are tissues?
    A group of cells that carry out specialized activities.

    - extremely tough - acts as a shock absober ex: ball and socket joints, intervertebral disc
  • Name the function and location of a Transitional Epithelium.
    FUNCTION: Accommodate Distension in the urinary tract and vaginal walls as fluid pressures vary. LOCATION: Lining of the ureters, urethra, and bladder.
