Throughout this lesson, you have interacted with text and graphs to collect evidence that the body has a set point for blood glucose and actively works to maintain balance when levels fall outside of the "normal" range. This idea of restoring balance is sometimes referred to as dynamic equilibrium, as dynamic refers to energetic or active - meaning that our body is maintaining stability for a set of internal conditions (blood glucose levels, temperature, pH balance, O2/CO2 levels, etc) by implementing lots of tiny changes.
But if we can't see our individual cells and our tissues in action, then how do we know these minute changes are actually occurring? Use the diagrams below to help you answer this question.
