Mammalian skin plays a vital role in maintaining homeostasis by regulating body temperature through the process of thermoregulation. It accomplishes this through two primary mechanisms: sweating and vasoconstriction/vasodilation. Sweating enables the body to cool down as sweat evaporates from the skin's surface, dissipating excess heat. On the other hand, vasoconstriction reduces blood flow to the skin's surface, conserving heat in colder environments. By balancing these processes, the skin helps ensure a stable internal body temperature, allowing mammals to adapt to varying external conditions and maintain their physiological equilibrium.
