    1. WHICH LEADS TO HEART ATTACK
9. TYPE 2 DIABETES
  1. OCCURS WHEN YOU BECOME OVERWEUGHT
  2. YOU CAN'T CONTROL BLOOD SUGAR
  3. HAPPENS WHEN INSULINE IS NOT RECOGNIZED BY THE CELLS
PATHOGENS AND DISEASE
1. MICROORGANISM
  1. BACTERIA
    1. PRODUCE TOXIN
      1. POISONS
  2. VIRUSES
    1. VIRUSES INFECT BODY CELL
      1. START TO REPRODUCE
        BREAK BODY CELL
  3. FUNGI
  4. CAUSE DISEASE
    1. PATHOGENS
  5. HOW DOES THE BODY DEFEND ITSELF?
    1. WHITE BLOOD CELL
      1. INGEST PATHOGENS
      2. PRODUCE ANTIBODIES
      3. PRODUCES ANTITOXIN
2. ENZYMES ARE CHEMICALS THAT ARE ABLE TO BREAK DOWN AND DIGEST PATHOGENS
3. MMR IS AGAINST MEASLES, MUMPS,RUBELLA
DRUGS TO TREAT DISEASE
1. ANTIBIOTICS KILL INFECTIVE BACTERIA IN THE BODY
  1. PENICILLIN IS AN ANTIBIOTIC WHICH WAS DISCOVERED BY ALEXANDER FLMING IN 1828

3. PAINKILLERS AND OTHER DRUGS RELIEVE SYMPTOMS OF A DISEASE

1. SOME PATHOGENS CAN MUTATE (CHANGE)
  1. PARTICULARLY VIRUSERS
  2. THEY MUTATE RESULTING A FORM CALLED MUTATION
  3. FEW PEOPLE ARE IMMUNE TO THESE CHANGED PATHOGENS
    1. SO DISEASE CAN SPREAD QUICKER
      1. DISEASE THAT SPREAD WITHIN A COUNTRY RESULT IN AN EPIDEMIC
      2. DISEASE THAT SPREAD ACROSS COUNTRIES RESULT IN PANDEMIC
  4. MRSA 'super bug' IS A BACTERIUM THAT EVOLVED THROUGH NATURAL SELECTION
    1. MRSA AND OTHER BACTERIA HAVE BECOME RESISTANT TO THE COMMON ANTIBIOTICS
IMMUNITY
1. DEAD/INACTIVE FORMS OF PATHOGEN ARE USED TO MAKE VACCINE
  1. VACCINE CAN BE INJECTED INTO THE BODY
    1. WHITE BLOOD CELLS REACT
      1. PRODUCING ANTIBIOTICS
      2. THIS MAKES THE PERSON IMMUNE
        PREVENTS FURTHER INFECTION
        THE BODY RESPONDS QUICKLY BY PRODUCING MORE ANTIBODIES
        ANTIBODIES RECOGNISE THE ANTIGEN ON THE PATHOGEN
