What is the primary function (purpose) of the human nervous system ?
Helps blood circulate through the body and allows for cellular respiration to take place.
Uses electrochemical signal to help parts of the body communicate with each other and react rapidly to changes both inside and outside the body.
Provides support to the muscles and glands and communicates through chemical signals released into the blood stream.
Allows for problem solving and the ability to read and write.
