- - - - memory B cell
      - plasma cell
      - immune cell activation by antigen
        
        produce antibody and attach to specific antigen
      - cell maturation in bone marrow (lymphoid organ)
    - - destroy cancer cell
      - control viral infection
      - cell maturation in thymus(lymphoid organ)
      - Helper T cell
      - Memory T cell
      - cytotoxic T cell
        
        NOT phagocyes
        
        release enzyme that kill the cell
        
        defend against the infected cell
        
        KILLER CELL
    - - destroy cancer cell
      - circulate in blood, and kill viruses, bacteria and blood cells
      - phagocytes
      - kill body cells that are not producing MHC1
- - - - Trap and phagocytes foreign substances and cellular debris
  - - - increases blood flow to damaged tissues,
        resulting in swelling and inflammation.
