What is the main function of the nervous system?

Explanation:
The nervous system coordinates and controls the body's activities through rapid nerve signals. It gathers information from senses and internal conditions, processes it, and sends quick commands to muscles and organs so you can move, react to pain, maintain balance, and regulate functions like heart rate. Hormone production comes from the endocrine system, which uses chemical messengers rather than electrical signals. The nervous system can influence digestion, but its primary role is not to regulate digestion. Filtering blood is done by the kidneys (and liver). So the main function is to control body activity through fast, coordinated communication.
