2) Sweating- sweat glands release sweat to evaporate from the skin to cool off body
3) Hair lies flat so no pockets of insulating air can be made to trap thermal energy
4) Vasodilation- arterioles dilate, more blood near the skin surface, more heat being radiated away from body]]> 2022-11-03 15:50:51 UTC https://padlet.com/kadiecory/rk5ig6vk6bhfqbng/wish/2368709877 https://padlet.com/kadiecory/rk5ig6vk6bhfqbng/wish/2368710429 2022-11-03 15:51:10 UTC https://padlet.com/kadiecory/rk5ig6vk6bhfqbng/wish/2368710429 Hormones https://padlet.com/kadiecory/rk5ig6vk6bhfqbng/wish/2368712354 https://www.bbc.co.uk/bitesize/guides/zxhktv4/revision/2]]> 2022-11-03 15:52:14 UTC https://padlet.com/kadiecory/rk5ig6vk6bhfqbng/wish/2368712354 https://padlet.com/kadiecory/rk5ig6vk6bhfqbng/wish/2368712532 vasodilation]]> 2022-11-03 15:52:21 UTC https://padlet.com/kadiecory/rk5ig6vk6bhfqbng/wish/2368712532 https://padlet.com/kadiecory/rk5ig6vk6bhfqbng/wish/2368714004 vasoconstriction]]> 2022-11-03 15:53:12 UTC https://padlet.com/kadiecory/rk5ig6vk6bhfqbng/wish/2368714004 What happens when the body is too cold? https://padlet.com/kadiecory/rk5ig6vk6bhfqbng/wish/2368717303 1)  Thermoreceptors detects the drop in body temperature and the hypothalamus initiating several heating mechanisms.
2) Sweat stops producing
3) Shiver- body uses these rapid short muscle movements require energy from respiration producing more thermal energy, 4) Hair stands up straight to make pockets of air that act as insulation 
5) Vasocontraction occurs where the arterioles contract and less blood is near the surface of the skin so less heat is radiated from the body.]]> 2022-11-03 15:55:06 UTC https://padlet.com/kadiecory/rk5ig6vk6bhfqbng/wish/2368717303 https://padlet.com/kadiecory/rk5ig6vk6bhfqbng/wish/2368717575 hormones= chemical messengers= produced in glands= released into bloodstream]]> 2022-11-03 15:55:14 UTC https://padlet.com/kadiecory/rk5ig6vk6bhfqbng/wish/2368717575 What happens when the body is too cold? https://padlet.com/kadiecory/rk5ig6vk6bhfqbng/wish/2368718745 1) Same as when the body is too hot
2) Sweat glands stop releasing sweat
3) Hair sticks up to trap a pocket of air
4) Vasoconstriction - blood vessels constrict, letting less blood through so less heat is lost]]> 2022-11-03 15:55:54 UTC https://padlet.com/kadiecory/rk5ig6vk6bhfqbng/wish/2368718745 https://padlet.com/kadiecory/rk5ig6vk6bhfqbng/wish/2368718840 Thermoregulation is a negative feedback - whenever change occurs in a system, it is automatically corrected to the original state]]> 2022-11-03 15:55:58 UTC https://padlet.com/kadiecory/rk5ig6vk6bhfqbng/wish/2368718840
