QCE Biology — Unit 3

Homeostasis — Flashcards & Quiz

Homeostasis is the maintenance of a relatively stable internal environment and underpins QCE Biology Unit 3. You need to describe negative feedback loops using the stimulus-receptor-control centre-effector-response model, and apply the framework to specific examples such as thermoregulation, osmoregulation and glucose regulation. Strong responses name the hormones and organs involved and explain how they correct disturbances back toward the set point.
