B3 - overall mind map of topics

This is a mind map which I was asked to do for homework. I quickly did a mind map which is very brief but should cover the main areas of the AQA B3 exam.

  • B3
    • Osmosis
      • diffusion of water
        • through a partially permeable membrane
      • from area of high to low concentration
      • allows water molecules through but stops soluble molecules
    • Active Transport
      • from an area of high to low concentration
      • requires energy from respiration
    • Exchanging materials
      • large surface area
      • well  ventilated
      • being thin - provides short diffusion path
      • efficient blood supply
    • Breathing System
      • lungs   ribcage trachea bronchus bronchiole diaphragm alveoli
      • exchanges O2 and CO2
      • breath in- ribcage moves up and out, diaphragm flattens
      • breath out- ribcage moves down and in, diaphragm pushed upwards by abdomen
    • Plants
      • guard cells control stomata
        • stomata let CO2 in and O2 out
      • Transpiration- movement of water
      • Phloem & Zylem
    • Circulatiory System
      • Heart
        • right & left atria and ventricles
        • Made from muscle tissue
        • Valves prevent backflow
      • Blood Vessels
        • Arteries
        • Veins
        • Capillaries
        • Blood
          • White blood cells
          • Plasma
          • Platelets
          • Red blood cells
    • Homeostasis
      • Waste materials - urea- broken down amino acids
        • Kidneys
          • Dialysis machine
            • must be done at regular intervals
          • Transplant
            • can be rejected by the recipient
      • Body temperature - thermoregulatory centre
      • Water and ion content
      • Glucose levels
        • Diabetes
          • Insulin
    • Environment
      • Global warming
      • Pollution
      • Deforestation
      • Biofuels
      • Food
        • Fishing
          • Sustainable
        • Food Miles
        • Mycoprotein
