==Key Stage 4==
===Meaning===
[[Thermoregulation]] is the process of keeping the [[temperature]] inside an [[organism]] constant.

===About Thermoregulation===
: [[Thermoregulation]] is a type of [[homeostasis]].
: [[Thermoregulation]] is controlled by the [[skin]].
When the [[Body Temperature|body temperature]] is too high:
*[[Sweat Gland|Sweat glands]] on the [[skin]] [[secrete]] [[sweat]] which [[evaporate]]s from the [[skin]] cooling it down.
*[[Erector Muscle|Erector muscles]] relax allowing the body hairs to lie flat on the [[skin]].
*[[Blood Vessel|Blood vessels]] near the surface of the [[skin]] [[dilate]] to allow more of the warm [[blood]] to pass its [[Thermal Energy Store|thermal energy]] on to the [[skin]].

When the [[Body Temperature|body temperature]] is too low
*[[Sweat Gland|Sweat glands]] stop [[secrete|secreting]] [[sweat]] and the [[skin]] becomes dry.
*[[Erector Muscle|erector muscles]] contract causing body hairs to stand on end. This creates a pocket of trapped air under the hairs which insulates the body.
*[[Blood Vessel|Blood vessels]] near the surface of the [[skin]] [[constrict]] reducing [[blood]] flow close to the [[skin]] preventing [[Thermal Energy Store|thermal energy]] being lost to the [[skin]].
