Homeostasis

Homeostasis is one of those important phenomena that everyone takes for granted. It ensures that several of the conditions in our body are strictly regulated without us realizing. One of the prime examples is the regulation of our body temperature. When our internal temperature rises above the normal, our blood vessels undergo vasodilation, where they dilate so that the blood flows closer to the skin surface. This allows heat from the blood to escape through the skin. Another way to reduce the heat is through sweating. The sweat glands produce sweat, which reaches the surface of the skin and evaporates, taking the latent heat with it. Conversely, a drop in our body temperature causes our blood vessels to undergo vasoconstriction, which is the narrowing of the blood vessels to keep the blood from losing its heat. We also shiver, which generates heat in our body.
