Exposure to extreme temperatures triggers physiological responses like shivering or sweating, ensuring a constant core temperature. Homeostasis also extends to regulating blood pressure and sugar levels.

The liver, kidneys, and sweat glands help remove excess hormones. Negative feedback loops, where hormone action suppresses further hormone release, play a crucial role in maintaining hormonal balance and homeostasis.

Feedback mechanisms can encourage (through positive feedback) or discourage (negative feedback) what is going on inside the organism.
