controlling blood glucose

• eating sugary foods or one ones high in carbohydrates release glucose into the the blood from the small intestine. metabolism of cells will remove this glucose from the blood.
• during vigorous excercise glucose is used up even more to increase the rate of respiration
• excess glucose is stored in the liver and muscles as glycogen. if glycogen stores are full glucose is converted into lipids in tissues. changes in the blood glucose concetration are monitored by the pancreas
• if the concentration of blood glucose is too high in the blood this is detected by the pancreas. the pancreas triggers the release of insulin into the blood stream. insulin converts glucose into glycogen which is stored in the liver and muscle cells. glucose levels drop
• if blood glucose levels are too low this is detected by the pancreas which trigger glucagon to be released into the bloodstream which convert glycogen into glucose on the liver and released into the bloodstream. glucose levels rise
