1. body system that breaks down food and absorbs nutrients
2. changing the position or location of the entire body
4. reproduce offspring- (sperm and oocytes)

6. the transfer of an organ or tissue from one person to another or from one body to another
8. environment outside an organization's boundaries that might affect it
9. protects and supports body organs and provides a framework that muscles use to support movement
