Mechanisms of Temperature Control
The body uses specific physical actions to gain or lose heat energy to stay at 37°C.
What is the purpose of shivering?
What is Mechanisms of Temperature Control?
"Thermoregulation mechanisms are the automatic physiological processes used to maintain internal body temperature."
Which response helps cool the body when body temperature is too high?
What happens when the body is too cold?
Which part of the body monitors and controls body temperature?
Heating and Cooling
Vasodilation: Blood vessels near the skin widen to lose heat via radiation.
Sweating: Water evaporates from the skin, taking heat energy with it.
Vasoconstriction: Blood vessels narrow to reduce heat loss to the surroundings.
Sweating is an endothermic process; it takes in heat from the skin to evaporate the water.
