How does the human body maintain homeostasis regarding temperature?

Let's think about homeostasis in terms of body temperature. Most animals maintain, or hold, their temperature at a certain level. For humans, this is about 98.6°F (37°C). When your hypothalamus senses that you're too hot, it sends signals to your sweat glands to make you sweat and cool you off.
