# Cells and Systems Word Search

This word search reviews the vocabulary of Unit B: Cells and Systems. As you scan the grid, you will meet the body systems that keep an organism running, respiration, circulation, digestion, and excretion, along with the cell processes and structures that make those systems work ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17321), [Topic](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17317)). Look for CIRCULATION and DIGESTION as reminders of how blood carries oxygen and nutrients while the body breaks down food ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17321)), and for DIFFUSION and MEMBRANE as reminders of how gases and liquids move into and out of cells ([Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17320), [Outcome](https://goa-cc-uat-aili-app-001.azurewebsites.net/explore/node/17320)).
