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.

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