(I)GCSE 2.77 b) Thermoregulation



- Negative feedback loop = control and maintaining constant conditions
- Co-ordinator = body temp of 37 - 38 d.c.
- Receptor of body temperature = Hypothalamus of the brain
- Hypothalamus responds to temperature of the body/ blood
- Change in temperature brought about by receptor = skin
- Response = increase/ decrease in body temperature
