Control of blood glucose levels

• Type 1 Diabetes: When the pancreas doesn't produce enough insulin so blood glucose levels increase
• Type 2 Diabetes: When the cells in your body don't respond to insulin and the pancreas not producing enough of it
• What is the main difference between Type 1 and 2 diabetes?


  • Type 1 is where you don't produce insulin
  • Type 2 is where your cells don't respond to insulin
  • Type 2 is caused by and unhealthy lifestyle or genetics
  • Type 1 is caused by an autoimmune reaction
• What hormones are secreted by the pancreas top help regulate blood glucose levels?

  • Insulin
  • Glucagon
• What happens when blood glucose levels get too high?


  1. Receptors detect levels and the Pancreas will secrete insulin
  2. The body will respond to insulin by absorbing more glucose
  3. The excess will be turned into glycogen and stored in muscles and liver
• What happens when blood glucose levels get too low?

  1. Receptors detect levels and the pancreas will secrete glucagon to break down the stored glycogen
  2. Restores glucose levels back to normal
