The video tutorial explains how the human body maintains a steady temperature through homeostasis, even when exposed to extreme temperatures. It describes the body's mechanisms for staying warm in cold conditions, such as shivering and redirecting blood flow, and cooling down in heat through sweating. The video also touches on other forms of homeostasis, like blood pressure and blood sugar regulation, highlighting the body's ability to maintain equilibrium.
