Studied by 0 peopleWhere is body temperature controlled in the body?
By the thermoregulatory center in the hypothalamus of the brain.
How is temperature monitored by the body?
Thermoregulatory center has receptors sensitive to blood temperature.
Skin has receptors sensitive to skin temperature - sends impulses to thermoregulatory center.
What physiological changes occur when the body temperature is too high?
Vasodilation: blood vessels near the surface of the skin dilate - more heat is radiated away.
Sweating: evaporation of water takes away heat energy from the surface of the skin.
What physiological changes occur when the body temperature is too low?
Vasoconstriction: blood vessels near the surface of the skin constrict - less heat radiated away.
Shivering: respiration allows muscles to contract. It is an exothermic process, so heat energy is released.
Sweating stops.
