Question

Let's start here
Let's start by going to the homeostasis simulation, linked HERE.

Read the information in the box to the left of that screen.

In this activity, it’s up to you, not the body, to maintain homeostasis in a virtual person. Gauges show current conditions in the body. To achieve homeostasis, click the left or right arrows to adjust heart rate, respiration, blood vessel dilation, perspiration, or blood sugar hormone release.

Your goal is to keep the dials centered. Click the button for each body system feature to learn more about that body system.

Don‘t become complacent when you achieve a balance! Our person will randomly change states and display a new set of conditions.

You will complete the homeostasis activity three time, then answer questions about your experiments.
