  • Controlling Glucose Levels:
    • How it get transported and what is it for? (Glucose)
      • Glucose is a sugar in your body which allows you to respire as well as helping your CNS work properly.
      • Glucose is carried through your blood, Dissolved in your plasma.
    • Where your glucose levels are monitored:
      • Your pancreas (Which is part of your Digestive system) monitors your glucose levels in your blood
        • Your pancreas is located underneath your stomach. If seen in colour it is a pale yellow and hard to spot at first view.
      • After eating food, Your glucose levels increase, Of course your pancreas detects this and releases a hormone in your body called insulin.
        • Insulin causes the spare glucose in your blood to be stored in your liver. Before this happens the excess glucose gets transferred to Glycogen.
        • If your glucose levels are too low, your pancreas releases a hormone called Glucagon which then reverses the glycogen to be turned back to glucose and be transported in your blood again.
    • Diabetes
      • Someone who is diabetic can not control their glucose levels.
      • There is two types of diabetes; There is type one and type 2.
        • Type One: They cannot produce insulin so need injections to lover glucose in their blood. This is mostly common in young people.
        • Type Two: This one creates insulin but the cells do not respond to this. They need to keep careful with diets to fix this but also tablets of insulin can be used as well. This is more common in older people.
      • If glucose levels get too high it can be told by your urine. If so this could be serious.
      • You can test your glucose levels by using a blood meter. It would tell you exactly how much you have in your blood and if it is too high would advise you take an insulin injection.
        • Insulin tablets wouldn't work because of the fact they would be digested before they get to the liver.
