Skins functions for the body's thermodynamics?

The skin plays a crucial role in the body's thermoregulation by acting as a barrier and facilitating heat exchange. It helps maintain a stable internal temperature through processes such as sweating, which cools the body via evaporation, and vasodilation, where blood vessels widen to release heat. Conversely, in cold conditions, vasoconstriction occurs to preserve heat. Additionally, the skin's insulating properties help reduce heat loss, ensuring the body maintains its optimal temperature for physiological functions.
