Explain how blood glucose is kept constant through the actions of hormones.
What will be an ideal response?
The pancreas produces two hormones that operate to keep blood glucose levels within narrow limits-insulin and glucagon. Insulin is produced after meals and lowers blood sugar by causing certain cells to take up and store excess glucose. The liver stores glucose as glycogen. Glucagon is released by the pancreas when blood glucose is low, mobilizing the stored sources of glucose.
