AQA GCSE Biology - B5 What is homeostasis? The regulation of conditions inside the body to maintain a stable internal environment in response to changes in both internal and external conditions What things do automatic control systems regulate? Body temperature, blood glucose level and water content What are the three main components that work together in automatic control systems? Receptors, coordination centres and effectors What does negative feedback do? When the level of some...
