How does the body remain stable while everything around us changes?

We explore homeostasis and the sensors, control centers, and effectors that regulate variables such as temperature, blood glucose, and blood pressure. We also explain negative feedback and amplifying feedback mechanisms, showing how the body constantly responds, corrects, and adapts.

From a single cell to a complete organism, the human body is organized into interconnected levels that depend on one another.

In this opening episode of Flesh&Bones, we explore cells, tissues, organs, and organ systems, building a foundation for understanding how anatomy and physiology fit together. An introduction for medical students and anyone curious about how the human body is structured.
