2.Tissue major type (Epithelia (3.Characteristics :star: :warning:…

- - - - 4.epithelia contacts by cell junction :star:
        
        Tight junctions
        
        neighboring membrane cnnect each other like zipper
        
        Gap junctions
        
        Allow cell communication between cell
        
        Desmosomes
        
        anchoring junctions that prevent cells are separated by mechanical stress
    - - Always have one free surface and ex : microvilli in intestine
        cilia in trachea
    - - composed almost of cell
    - - Have no blood vessle but have nerve
    - - (1) have high level for regeerate
        (2) replace old or lost cell by cell
        division
    - - structure
        
        Reticular lamina (connective tissue)
        網狀層
        
        Basal lamina（epithelia)
      - Function
        
        help epithelia to against stretching and tearing forces
  - - - like cube
    - - like column
    - - flattened and scalelike
  - - - more one layers and relate filtration and absorption
    - - only one layer and relate protect ex: skin surface
  - - - Skin , Kidneys
    - - Kidneys
    - - Digestive tract GI track
    - - Glands
  - - - Function
        
        Provides slick, friction-reducing lining
      - Location
        
        Blood vessel . lymph vessel .heart
      - structure :warning:
        
        Simple epithelial sheet of single layer squamous cells

        Description
        
        Moist membranes found in closed ventral body cavities and
        each serosa consists of parietal and visceral layers
      - Structure
