==Key Stage 4==
===Meaning===
'''Vasoconstriction''' is when [[Blood Vessel|blood vessels]] become narrower, allowing through a smaller [[Volume (Space)|volume]] of [[blood]].
===About Vasoconstriction===
: '''Vasoconstriction''' of [[capillary|capillaries]] in the [[skin]] takes place during [[thermoregulation]] when the [[Body Temperature|body temperature]] becomes too low. This reduces the amount of [[Thermal Energy Store|thermal energy]] lost via the [[skin]] to the surrounding environment.
