describe the role of the skin in temperature regulation, with reference to sweating vasoconstriction and vasodilation
our skin has many different sensors. our fingers tips have the greatest amount of sensors
they protect skin,stops too much water loss, help you keep your body temperature constant, stop germs getting in and ket you feel pain, temperature.
vasoconstriction: happens when cold, the blood vessels become narrower and the flow of blood is constricted, resulting in retained body heat. your skin turns paler as less blood is reaching the surface, reducing the radiation of heat.
vasodilation: happens when hot, blood vessels widen, resulting in increased blood flow and lower blood pressure
