Which body system coordinates the body's response to stimuli?

Which body system coordinates the body's response to stimuli?

• A. Circulatory system
• B. Digestive system
• C. Nervous system
• D. Respiratory system

Answer: (C)

The body’s ability to gather information from the environment and produce a quick, organized response is carried out by the nervous system. It uses networks of nerves to receive signals from sensory receptors, process that information in the brain and spinal cord, and send out commands to muscles or glands to act. This system handles both quick reflexes and deliberate actions, making it the primary coordinator of responses to stimuli. Other systems have important roles that support the body’s functions (for example, the circulatory system moves blood, the digestive system processes food, and the respiratory system manages gas exchange), but they do not coordinate the body's overall response to changes in the environment on their own.
