Control of blood glucose

    Cards (6)

    • Two hormones for controlling blood glucose levels?
      Insulin
      -produced by beta cells in pancreas
      -released when blood glucose levels are high
      Glucagen
      -produced by alpha cells in the pancreas
      -released when blood glucose levels are low
    • What happens When there is low blood glucose
      Hypoglycaemia- caused by too much insulin
      symptoms- dizziness, confusion, sweating, shaking and weakness
      could lead to death
    • What happens when there is high blood glucose?
      Hyperglycemia
      Symptoms- frequent urination, fatigue and blurred vision
      Can lead to nerve damage, kidney damage and heart dissease
    • What is blood glucose
      The concentration of glucose in the blood system, the primary source for energy in cells
    • What happens when food is eaten?
      -carbohydrates are converted into glucose causing increase in blood glucose
      -the pancreas releases insulin to use the glucose as energy
    • Describe how type 1 diabetes is controlled?
      -insulin injections
      Rapid action insulin- lowers blood sugar fast taken before meals
      Long acting insulin- steady release of insulin over a long period of time
