# Cells at Work

Your heart just beat, your lungs just expanded, and neither one asked for permission.

**Journal prompt: Pick one body system (respiration, circulation, digestion, excretion or sensory awareness) and explain how a single change in your day, like running for a bus, eating a big lunch, or stepping outside on a cold morning, changes what that system has to do ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17321)).**

### Where to start
- Which system did you pick, and what is its main job in the body?
- What specific organs or tissues are involved ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17321))?
- What actually changes: does something speed up, slow down, or produce more or less of something?
- Why does that change help your body stay balanced or healthy?

### Stretch
Zoom in to the cell level. Name one type of cell in that system and describe what it does differently during your chosen event ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17321), [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17320)).
