Storyboard Text

  • We are the first line of defense we need to make sure no germs can get in
  • A antigen just made it trough a cut
  • A antigen invalids a cell
  • while its travels the blood stream it multiples
  • The antigen get past the second line of defense the macrophages while its looking for things that dont belong
  • a helper T-cell from the third line of defense identifies the pathogen in the infected cell and calls for the killer T Cell to attack it and for the Macrophages from the second line of defense to come and take care of the antigen
  • B cells produce antibodies that remember the pathogen for quicker response the next time there's an invasion
