They become denatured, and stop working.
5 of 8
What is the hypothalamus?
The processing centre in the brain that controls the body temperature.
6 of 8
How does the body lose heat?
We sweat, which cools us once evaportaed. Blood vessels dilate, to allow heat energy to radiate from the body (vasodilation).
7 of 8
How does the body maintain heat?
Blood vessels constrict, to minimise heat loss by radiation (vasoconstriction). We shiver, which increases respiration in the muscles to produce heat. Hairs stand up to trap air for insulation.
