# How Do Your Cells Work Together?

Your body is made of trillions of cells, but you probably never think about what they're doing right now.

**Describe a system in your own body, such as your digestive system, circulatory system or respiratory system. Explain what job that system does and name at least two different types of cells or tissues that work together to get the job done ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17321)).**

### Where to start:

- What happens to food after you swallow it, or what happens to oxygen when you breathe it in?
- Which organs are involved in that process?
- What do you think the cells in those organs are doing to make the system work?
- How would that system fail if one type of cell stopped doing its job?

### Stretch:

Compare your chosen system to the same system in a different animal. How is the structure different, and how does that change what the system can do?
