> Eduqas GCSE Biology — 2.5.3 Homeostasis · Explain · 4 marks

## Mark scheme (4 marks)

1. Thermoreceptors / the thermoregulatory centre in the hypothalamus detects the rise in blood temperature
2. Sweat glands produce more sweat / increased sweating occurs
3. Sweat evaporates from the skin surface, removing heat energy from the body
4. Vasodilation occurs — blood vessels near the skin surface widen, increasing heat loss by radiation
