Explanation:
Detailed explanation-1: -Homeostasis describes how conditions within an organism are kept constant, in order to keep cells ticking over. The nervous system is responsible for maintaining homeostasis and is made up of neurones which connect our sense organs (such as our eyes and skin) to our brain.
Detailed explanation-2: -When you enter a cold environment, your body redistributes blood to the torso, protecting and maintaining the warmth of the vital organs there. At the same time, your body constricts blood flow to the skin. Narrowing the roads to the skin means less heat can make the journey, and so less is lost to the environment.
