The skin plays a large roll in maintaining homeostasis of body temperature.  The temperature range for homeostasis is housed in the [brain]. When body temperature is too [high], blood is shunted towards the [skin] and heat dissipates across the surface of the body into the atmosphere. When body temperature is too [low], blood is pulled back internally to protect the more important organs.  This leaves the extremities, like the [fingers], with less blood.
