Web7 sep. 2015 · If the core temperature decreases, or if the temperature receptors in the skin detect a decrease in the temperature of the surroundings, the hypothalamus sends impulses to several different effectors to adjust body temperature: Vasoconstriction - muscles in the walls of arterioles that supply blood to capillaries near the skin surface contract. WebThe rate of heat loss is largely determined by how rapidly the heat is: 1) carried from the core to the skin; 2) transferred from the skin to the surroundings. 3. Most heat is transferred from the core to the skin by convection in the blood, where it is then lost to the air & surroundings. 4.
