*** WHAT'S COVERED ***
1. Blood Glucose Concentration Regulation
* The need to maintain blood glucose within a specific range.
* The concept of homeostasis and negative feedback.
2. Role of Insulin
* Released by the pancreas when blood glucose is high.
* Stimulates cells (especially liver and muscle) to take up glucose.
* Promotes the conversion of glucose to glycogen for storage.
3. Role of Glucagon
* Released by the pancreas when blood glucose is low.
* Stimulates the liver to break down glycogen into glucose.
* Promotes the release of glucose into the bloodstream.
4. Interaction between Insulin and Glucagon
* How these hormones work antagonistically.
* Maintaining blood glucose levels through a negative feedback loop.
