Thermoregulation 3.0 / 5 based on 1 rating ? BiologyGCSEAQA Created by: mollieCreated on: 01-05-13 19:48 monitors the core body tempreture thermo regulatery system 1 of 8 body too hot, starts sweating, using energy turning water liquid into water vapour. 2 of 8 arteriols dilate to supply capillarity with greater blood flow vasoditation, cools body down. 3 of 8 more blood flowing near surface easier for heat to be radiated to surroundings and cool you down 4 of 8 normal core body temperature 37 degrees C 5 of 8 constricts Arterioles so less blood is near the surface vasoconstriction, reduces radiation to surroundings. cools body down 6 of 8 muscle contraction releasing heat energy, shivering to keep warm. 7 of 8 more fur in winter for animals traps more air as an insulator to keep warm. 8 of 8
