What is Homeostasis?

Homeostasis, a concept introduced by Claude Bernard, refers to maintaining a stable internal environment. The video uses the analogy of a plane's cockpit to explain how the brain regulates body functions. Key factors like temperature, blood sugar, ions, and waste levels must remain constant. The negative feedback mechanism helps restore balance when these factors deviate. This process is vital for enzyme function and overall metabolism, ensuring survival without conscious effort.

What is negative feedback and how does it work in the context of homeostasis?

Why is homeostasis important for our metabolism?
