Which body system processes and transmits information throughout the body?

• A. Digestive
• B. Nervous
• C. Circulatory
• D. Endocrine

Answer: (B)

Processing and transmitting information throughout the body is the nervous system’s main role. It uses neurons to carry electrical signals quickly from sensory receptors to the brain and spinal cord, which interpret the information and dispatch rapid commands to muscles and glands. This enables sensation, reflexes, movement, and thought. The digestive system breaks down food and absorbs nutrients, not signaling across the body. The circulatory system mainly moves blood and nutrients; it doesn’t process information. The endocrine system sends chemical messages via hormones, which coordinate activities but travel more slowly and are better for longer-term regulation. So, the nervous system best fits the idea of processing and transmitting information everywhere.
