- - - - Liver converts into glycogen
      - Removed by kidneys
  - - - Iron is stored
  - - - Products then removed by kidneys
- - - - Oxygen + glucose --> carbon dioxide + water + energy
  - - - Filters blood
- - - - Over/undereating, alcohol, smoking, lack of exercise, fatty diet
    - - Inherited from family
    - - Defense system malfunctions
        
        May react to dust, pollens
        
        Causes hayfever
        
        May react to gluten or dairy
        
        Eczema
      - Autoimmune disease
        
        Body reacts to own body tissues
    - - Eg. cancer
        
        Cell division is uncontrolled
    - - Infestations w/ worms, lice, tick, fleas
  - - - Bacteria, viruses, fungi, protozoa
        
        Malaria, thrush, chlamydia, influenza
      - Large numbers to destroy cells
      - Produces a poison (toxin); released in host
- - - - Living cells underneath
    - - Conjunctiva
    - - Trapped in mucus
    - - Blood washes area
        
        White blood cells swallow bacteria
        
        Dead cells produce pus
        
        If too many pathogens

        Sends a message to brain
        
        Effectors
        
        Response/reaction to nerve impulse received
      - Sensory neurons- lead away from receptors
      - Motor neurons- lead towards effectors
      - Dendrites receive impulses from axons
        
        Axon- carries impulses away from the cell body
  - - - Hormones
        
        Released directly into bloodstream
