What is the principle of negative feedback?Show answer
Homeostasis usually works by negative feedback: when a condition moves away from its normal level, the body detects the change and acts to bring it back. If something rises too high, the response lowers it; if it falls too low, the response raises it. Blood glucose control is the key example.
What is controlling blood glucose?Show answer
The level of glucose in the blood is controlled by the pancreas, using two hormones:
