4?

Agree with 4.

Yes, option 4) "coordinates body function: voluntary and involuntary" best describes the function of the nervous system. It is responsible for regulating and coordinating various bodily functions, both voluntary (controlled by conscious thought) and involuntary (automatically regulated). This includes transmitting signals to and from sensory organs and the brain, allowing for the coordination of movement and response to stimuli. It also helps in regulating heart rate, blood pressure, and other essential bodily processes.
