        First name describe number of layers
        
        2- stratified( more than one layer)
        
        Z
        
        1-simple ( one layer only)
        
        Silmple cuboidal
        
        Simple columnar
        
        Simple squamous
        
        Types:
        
        Endothelium: thin and flattened lining of some organs (heart,blood,lymphatic vessels)
        
        Mesotheliom: lines ventral body cavities and covers visceral organs(serosae)
        
        Function:
        
        1-passage of materials by passive diffusion(gas exchange in alveoli)and filtration(kidney capsule)
        
        2- secretes lubricating substance in serosae
        
        Single layer of flat cells with disc-shaped nuclei
        
        Location:
        
        1-alveoli of lungs and kidney capsule
        
        2-lining of heart,blood,and lymphatic vessels
        
        3-lining of ventral body cavity and covering organs(serosae)
        
        Last name describe the shape
  - - - 1-simple(one layer)
        
        Simple cuboidal
        
        function
        
        Secretion and absorption
        
        Location
        
        Kidney tubules
        
        Secretory portions of small glands
        
        Ovary surface
        
        Single layer of cube-like cells with large spherical central nuclei
        
        Simple columnar
        
        Function
        
        Absorption, secretion of mucus, enzymes,and other substances
        
        Propels mucus or reproductive cells by ciliary action(ciliated type )
        
        Location
        
        Ciliated: lines digestive tract(from stomach to anal canal),gallbladder,ducts of some glands
        
        Non-ciliated: lines digestive tract(from stomach to anal canal),gallbladder,ducts of some glands (note: that it contain microvilli( hair-like structure that does not move) which facilitate the absorption of ingested food and water molecules
        
        Single layer of column-shaped(rectangular)cells with oval nuclei
        
        Some bear cilia(hair-like structure that moves)at their apical surface(upper surface)
        
        May contain goblet cells
      - 2- stratified( more than one layer)
        
        Stratified cuboidal :
        
        Function:
        
        Protection
        
        ((2 layers)) of cube-shaped cells with spherical central nuclei
        
        Location
        
        Forms largest ducts of sweat glands, ducts of mammary glands, and salivary glands
        
        Stratified squamous
        
        Contain 2 or more layers of cells squamous in shape(deeper layers of cell appear cuboidal or columnar) -named according to the shape of cells at apical
        
        Types
        
        Keratinised: contain the protective protein (keratin) which forms the first layer of skin (epidermis)
        
        Non-keratinized: forms moist lining of the body openings( vagina,anus,mouth, and esophagus) and tubes where is wear and tear
        
        Location
        
        Keratinized: forms epidermis
        
        Non-keratinized: forms lining of esophagus, mouth, anal canal, and vagina
        
        Function
        
        Protects underlying tissues in areas subject to abrasion
        
        Stratified columnar
        
        Several layers; basal cells usually cuboidal while the superficial cells elongated with an oval nuclei
        
        Function:
        
        Protection and secretion
        
        Location :
        
        Rare tissue type because we can only found it in male urethra and large ducts of some glands
    - - 1-squamous (plate-like)
      - 2-cuboidal(like cubes)
