GCSE Biology - Homeostasis #54

The video explains homeostasis as the process of maintaining a stable internal environment in the body. It describes how automatic control systems, consisting of receptors, coordination centers, and effectors, help regulate conditions like temperature and glucose levels. The nervous and endocrine systems play key roles in communication. The concept of negative feedback is introduced, illustrating how it helps return body conditions to normal when they deviate from optimal levels.

In what ways can the body respond to external temperature changes?

How does the body ensure that glucose levels remain stable?

What happens when the body temperature rises above normal levels?
