  • Infectious Disease B1.2
    • Micro organisms
      • Viruses
        • Much smaller than bacteria
        • Enter the bodycells
          • They then infect it
            • Then reproduce inside it
              • The bodycell will then break open
        • Not all cause disease
          • Fungi
          • The ones that do are called PATHOGENS
      • Bacteria
        • Produce toxin(poisons)
        • Not all cause disease
          • Fungi
          • The ones that do are called PATHOGENS
      • Defends itself from pathogens
        • White Blood Cells
          • Ingest Pathogens
            • The WBC recognises the bacterium
              • Then surrounds bacterium
                • Then engulfs bacterium
                  • Then releases enzymes
          • Produce Antibodies
            • some bacterium have antigens
              • Antibodies have a shape that match the antigens
                • Antibodies attach to antigens
                  • And produces many copies
          • Produce Antitoxins
            • Antitoxins go to the toxins
              • and "deactivate it" To make the toxins harmless
    • White Blood Cells
