What are the three main functions of the nervous system?

Explanation:
The nervous system coordinates sensing, thinking, and acting. It first gathers information from receptors to detect changes in the body and environment (sensation). It then processes and interprets that information (integration). Finally, it produces a coordinated response, typically by signaling muscles or glands to act (response). This trio—sensory input, processing, and motor output—is what the nervous system does best. The other options describe functions of other systems. Hormone production belongs to the endocrine system, not the nervous system. Movement, circulation, and digestion involve multiple systems, and respiration is a function of the respiratory system.
