- 2. The body system that moves the body with the help of the skeletal system.
- 7. A biological occurrence wherein the output of a system amplifies the system or inhibits the system; allows homeostasis to be maintained.
- 8. The body system that provides a mean of producing offspring.
- 11. The chemical messenger of the body.

- 20. The body system that controls body functions through hormones.
Down
- 1. The smallest blood vessels in your vascular system; transport blood, nutrients and oxygen to cells in your organs and body systems.
- 3. The breakdown of food into smaller pieces without chemical change to the food molecules.
- 4. The body system that protects the body against invading organisms (think immunity).
- 5. The body system that removes cellular wastes from the body (think bladder).
- 6. A state of balance among all the body systems needed for the body to survive and function correctly.
- 9. These are tubelike structures that are responsible for the transportation of fluid to and from every organ in the body.
- 10. The body system that transports nutrients, fluids, and gases (ex. heart, arteries).
