Homeostasis is the maintenance of a constant internal environment i) Explain how shivering helps to regulate body temperate. ii) Explain how sweating helps to regulate body temperature (4 marks)

i) Explain how shivering helps to regulate body temperature. Shivering stops body temperature from falling when the external environment is cold (1)Shivering increases muscle contraction (1) Heat is generated through increased respiration/friction (1)ii) Explain how sweating helps to regulate body temperature. Sweating stops body temperature from rising when the external environment is hot (1) The sweat gland causes water to be secreted onto the surface of the skin (1) Heat is removed through evaporation of the water (1)
