Learning About
How is the optimum blood glucose level maintained?
Keywords:
  • Insulin: A hormone, produced by the pancreas, that regulates glucose concentrations in the blood. (1)
  • Gland: A gland is a group of cells in an animal's body that makes substances like hormones. (1)
  • Homeostasis: The maintenance of steady conditions. The ability of the body to maintain a constant internal environment, e.g. temperature and blood glucose concentration. (1)
  • Synapse: A tiny gap at the junction between two nerve cells, which nerve signals must cross. (1)

Blood glucose concentration is monitored and controlled by the pancreas What organ monitors and controls blood glucose concentration?

Draw life size model of a person to show control of blood glucose
If the blood glucose concentration is too high, the pancreas produces the hormone insulin that causes glucose to move from the blood into the cells. How does the pancreas control blood glucose levels?
In the liver and muscle cells excess glucose is converted to glycogen for storage. What do the liver and muscle cells do to excess glucose?
When insulin is released it causes the liver to convert more glucose into glycogen. How does insulin control blood glucose levels?
Type 1 diabetes is a disorder in which the pancreas fails to produce sufficient insulin. It is characterised by uncontrolled high blood glucose levels and is normally treated with insulin injections. What is type 1 diabetes and how is it treated?
In Type 2 diabetes the body cells no longer respond to insulin produced by the pancreas. A carbohydrate controlled diet and an exercise regime are common treatments. What is type 2 diabetes and how is it controlled?

Demo: How doctors used to diagnose diabetes by tasting fake urine. Confirm results with Benedict’s solution. Evaluate the methods.
Obesity is a risk factor for Type 2 diabetes. Which diabetes is obesity a risk factor for?
Students should be able to compare Type 1 and Type 2 diabetes and explain how they can be treated.

GF/EW: How has treatment of diabetes developed over time? include use of human insulin produced by bacteria, current research into pancreas cell transplants and stem cell research.
Students should be able to extract information and interpret data from graphs that show the effect of insulin in blood glucose levels in both people with diabetes and people without diabetes.

(HT only) If the blood glucose concentration is too low, the pancreas produces the hormone glucagon that causes glycogen to be converted into glucose and released into the blood. (HT) How does the body increase the blood glucose concentration?
(HT only) Glucagon interacts with insulin in a negative feedback cycle to control blood glucose (sugar) levels in the body. (HT) How does glucagon control blood glucose levels?
