Maintain Homeostasis How hard does your body work to maintain blood sugar concentration?
The Players • Pancreas • Produces hormones insulin and glucagon • Liver • Stores blood sugar as glycogen Produces the hormones insulin and glucagon • Fat • Cells can store sugar when excess is in the blood
What should your blood sugar be? • 70-125 mg/dL (units common sugar tests use) which equals < 7.0 mmol/L • When would it be ok for your sugar to be on the higher end? When should it be at the lower end of this range?
Feedback • How your body responds to changing conditions. • EX: • High Blood Sugar: Turns ON insulin and turns OFF glucagon production.
Practice: Connecting Concepts • Turn to your partner. You have just “tested” his/her blood sugar. The value is written on the board. • Use your notes to discuss what SHOULD be happening to bring his/her blood sugar into the normal range.
