Final answer:
Insulin and glucagon are hormones that maintain blood glucose concentration. When it rises too high, insulin is released to remove glucose from the blood. When it falls too low, glucagon is released to release glucose into the blood.
Step-by-step explanation:
Blood glucose levels are tightly maintained between 70 mg/dL and 110 mg/dL in the body through the actions of insulin and glucagon, two hormones produced by the pancreas. If blood glucose concentration rises above the normal range, insulin is released, which stimulates body cells to remove glucose from the blood. On the other hand, if blood glucose concentration drops below the normal range, glucagon is released, which stimulates body cells to release glucose into the blood.
