  • The macrophages find the bacteria with the antibodies attached to them and put to death the bacteria by way of phagocytosis.
  • The T helper cells know that there's a problem and they send cytokine for B cells.
  • The macrophages show the T helper cells what they ate up.
  • go!
  • When a match is found, the B cell makes multiple copies of the antibody it has on the surface.
  • Once the antibodies are attached to the antigens on the bacteria cell, the cytokine is sent to get more macrophages.
  • Meanwhile, the B cell that recognized the antigen is replacing and making memory cells with the same antibody on them so that if this bacteria comes back they can recognize it more quickly and destroy it.
