    • Human biology
    • Diet
      • Provide energy body needs but no more
  • Balanced diet
    • Provide energy body needs but no more
    • Carbs-energy
      • Fat-Keep warm and energy
        • Protein-Growth,cell repair and replacement
  • Carbs-energy
    • Fat-Keep warm and energy
      • Protein-Growth,cell repair and replacement
  • Fibre-Keep your digestion system moving
  • Metabolic rate
    • Diet and metabolic rate
      • Diet
    • The speed at which they occur is your metabolic rate
    • More energy =  higher metabolic rate
      • The speed at which they occur is your metabolic rate
    • Factors affecting health
      • Unbalanced diet
    • Poor diets lead to malnutrition
      • Unbalanced diet
    • Malnutrition leads to you being fat or thin
    • Too much saturated fat can increase blood cholesterol level
      • Malnutrition leads to you being fat or thin
    • Too much salt can cause high blood pressure and heart problems
      • Too much saturated fat can increase blood cholesterol level
      • They can also affect their blood cholesterol level
        • Inherited factors can affect your metabolic rate
      • Inherited factors
        • Inherited factors can affect your metabolic rate
        • Factors affecting health
        • Fighting disease
          • Bacteria
            • Fighting disease
            • They damage cells and produce toxins
            • Viruses
              • They are not cells
                • They hijack your cell and copy themselfs
            • Defense system
              • The skin, hair and mucus in the respiratory tract
            • Platelets help blood clot to seal the wound quickly
              • White blood cells have three lines of attack
                • Consume them
                • Produce antibodies
            • Bacteria can mutate
              • Resistant bacteria
              • This bacteria can reproduce and pass on this strain
              • Synapses and reflexes
                • Synapses
                  • Synapses and reflexes
                    • The connections between 2 neurons
                      • The nerve signals transferred by 2 chemicals which diffuses across the gap
                        • Set off electrical signal to next neurone
                  • Reflexes
                    • Reflexes are automatic responses to certain stimuli
                      • The passage of information in a reflex called a reflex arc

                  This mind map is well organised and summarises the key facts in the AQA GCSE Human Biology unit the nervous system, disease and drugs. This would also be useful for any biology student studying these topics. It might be useful to add little images to this map so that it becomes even more memorable.
