- - - - Fibroblasts - Most abundant cells, maintain the connective tissue fibers
        Macrophages - "big eater", Macrophages are drawn to the affected area
        Fat cells - "adipocytes"
        Mast cells - small, near the blood vessels, filled with chemicals that are released to begin the bodys defensive activities after an injury or infection
- - - - Smooth & cardiac muscle + ciliated epithelia
- - - - A single layer of elongated cells with bascally located nuclei -- Functions; - protection, absorption, secretion -- location - lining small intestine, lining uterus -- free surface - microvilli, goblet cells
      - Stratifited squamous epithelia
        
        Many layers of flattened cells -- function- protection - Non keratinized -location- lining mouth, lining throat, lining vagina, lining anus -- keratinized - epidermis of skin
        
        Stratified Cuboidal epithelia
        
        2-3 layers of cuboidal cells -- locations - mammary glands, sweat glands, salivary glands, pancreas
        
        Stratified columnar epithelia
        
        2-3 layers of elongated cells-- locations - vas deferens, part of male urethra
        
        Pseudostratified columnar epithelia
        
        A single layer of elongated cells with scatered nuclei, all cells touch the basement membrane -- functions - secretion,protection -- location - lining trachea, lining fallopian tube--free surface -- cilia, goblet cells
        
        Transitonal epithelia
        
        many layers of cells that change shape in response to tension -- function - distensibility -- location- lining urinary bladder and ureters
