1. Controlling Blood Sugar How do we control blood sugar and what can go wrong ? Starter: What do these people have in common? Has it affected their lives?

2. Glossary Insulin: A hormone that removes excess glucose from the blood. Higher: Glucagon: a hormone involved in the control of blood sugar levels.

3. Check point- what is the best definition for homeostasis 1) Sweating to keep our bodies cool. 2) The maintenance of a constant internal environment. 3) The process that makes our body move.

4. What is a hormone?  Hormones are chemical messengers used in the body by the endocrine system.  Hormones are produced by our glands.  Which gland produces the hormone insulin? Pancreas

5. The Pancreas  Insulin controls........  Why do we need to keep our blood sugar level constant? blood sugar levels in our bodies. Copy this down into your books

7. Glucose levels in the blood

8. Changing glucose levels After a meal the level of glucose in our bodies [increases/decreases]? After exercise the levels of glucose in our bodies [increases/decreases]? Why do you think this happens? I think this happens because......................

9. Why is breakfast the most important meal of the day? Time Blood Glucose Levels

10. Time Blood Glucose Levels Time Blood Glucose Levels Eat loads of haribo Exercise

11. Changing glucose levels - notes After a meal the level of glucose in our bodies increases Insulin is produced by the pancreas which makes the liver turn glucose into glycogen which is stored in the liver. After exercise or a long time after a meal, the levels of glucose in our bodies decreases HIGHER ONLY : Glucagon is produced by the pancreas which makes the liver turn glycogen back into glucose so our cells can carry on respiring.

18. Type 1 Diabetes Born with this. Pancreas does not make enough insulin. Blood glucose gets very high and glucose is lost in urine. No glucose means you get tired. Weight loss because fats are broken down. Treatment Injections with insulin before a meal. This allows glucose to be converted into glycogen and stored. Prevents the level of glucose getting too high. Pancreas transplant – difficult and limited success.

19. Type 2 Diabetes Develops later in life. Poor diet, lack of exercise, obesity. Body stops making enough insulin or stops recognising it. Consequences: Frequent urination. Weight loss. Arteries harden leading to heart failure. Treatment Controlled diet and exercise programme. Carry a sugary drink in case of emergencies. http://www.nhs.uk/Condit ions/Diabetes- type2/Pages/Graces- story.aspx

20. Activities Option 1) Write down who the diabetic patient is and design a meal suitable for them. Use the information I have given you and that out of the book. Justify each piece of the meal with a reason for your choice. You can use some of the equipment to help inform your meal. 2) complete the worksheet and answer the questions on controlling glucose levels. 3) Complete the activities on the computer. (pairs at a time). 4) Produce a revision poster and use diagrams to explain the control of blood sugar in your body. 5) extension challenge: see me when you have done 1,2, 3 or 4.
