  8. 12. System: The system that controls and coordinates body activities; includes the brain, spinal cord, and nerves.
  9. 16. An organ in the digestive and endocrine systems that produces insulin and digestive enzymes.
  10. 18. Stem: The lower part of the brain that connects to the spinal cord; controls basic life functions such as breathing, heartbeat, and digestion.
  11. 19. System: The body system that includes the skin, hair, nails, and glands; protects the body and regulates temperature.
