Immune System

  • step 1

    First exposure to a pathogen
  • step 2

    a white blood cell called a macrophage consumes the pathogen and displays it's antigen
  • step 3

    Antigen exposure activates helper T-Cells. Helper T Cells activates B-Cells killer T Cells and create memory T Cells
  • step 4

    Plasma cells produce and release antibodies
  • step 5

    Memory b cells recognize a particular pathogen if it returns and rapidly creates plasma cells
  • step 6

    Killer T-Cells hunt body cells that are infected and kill those cells
  • step 7

    Suppressor t cells inhibit (stop) cell mediated immune response once the infection is under control
  • step 8

    Memory t cells recognize particular pathogens if it returns and rapidly creates killer t cells
