I gave my students this multiple choice question: The nervous system consists of the brain, spinal cord, and nerves that run throughout the entire body. Which of these is one function of the nervous system?

Only one answer is correct among these 4 choices:
- supports body posture
- controls body functions
- supplies the blood with oxygen
- carries blood to and from the heart

Could you tell me which one is correct?

controls body functions
