- Controlling Blood Glucose
- Insulin and glucagon control blood glucose level
- Normal metabolism of cells removes glucose from the blood
- Vigorous exercise removes more glucose from the blood
- Changes in blood glucose are monitored and controlled by the PANCREAS using the hormones insulin and glucagon
- Glucose levels in blood to high, insulin added
- Insulin makes liver turn glucose into glycogen
- Glucose levels in blood too low, glucagon is addded
- Glucagoon makes liver turn glycogen into glucose
- Glucose levels in blood to high, insulin added
- Type 1 diabetes- a lack of insulin
- Pancreas produces little or no insulin
- A person's blood glucose can rise to a level that can kill them
- Controlling it
- Avoiding foods rich in simple carbohydrates e.g sugars. Exercise after eating to use up extra glucose produced during digestion
- Injecting insulin into blood at mealtimes, so the liver will remove the glucose as soon as it enters the blood from the gut as the food is digested: EFFECTIVE
- Amount injected depends upon a person's diet and how active they are
- Human insulin made by genetic engineering
- Helps control blood glucose levels but patient may still have long term health problems
- Pancreas transplant
- Disadvatages: Immuno suppressants needed which often have serious side affects
- Experimenting with artificial pancreases and stem cell research
- Pancreas produces little or no insulin
- Insulin and glucagon control blood glucose level
