Glucose rises above normal

• If the glucose concentration rises above normal, the beta cells of the islets of Langerhans detect this increase and respond by secreting insulin into the blood
• Insulin:

  • stimulates the absorption of glucose from the blood into the body cells
  • stimulates the conversion of glucose to glycogen in the liver and muscles
• Glucose is removed from the blood which causes the glucose concentration to decrease
• The decrease in the glucose concentration is detected by the beta cells, which in turn, inhibit the secretion of insulin
