  • Infectious Disease
    • Caused by pathogens
      • Fungi
      • Bacteria
      • Viruses
      • Protozoa
    • Malaria
      • Caused by a protozoan, which is a parasite.
      • They are vectors and carry round the disease without them getting it.
      • Mosquitoes carry the disease so we can prevent them from coming near us and infecting us. This includes nets and spraying water with insecticide.
    • Immune System
      • Pathogens will reproduce until they are destroyed.
      • How your Immune System deals with pathogens:
        • CONSUMES THEM
          • PRODUCES ANTITOXINS
            • PRODUCES ANTIBODIES
              • When a foreign antigen is present, the body will produce antibodies and destroy the new cells.
            • Counters the effects of toxins.
          • White blood cells engulf and digest them
