The body system responsible for perception and sensation, including sight and hearing, is called what?

• A. Nervous
• B. Integumentary
• C. Digestive
• D. The Senses

Answer: (D)

Perception and sensation come from the senses—the group of organs and pathways that detect stimuli from the environment and send signals to the brain. Sight and hearing are classic examples: light is detected by the eyes and sound by the ears. Sensory receptors convert these external cues into neural signals that the brain interprets as perception. While the nervous system processes and integrates this information, the part that best describes the collection of sensing organs and their role in sensing the environment is the senses. The other options refer to systems with different primary roles: the nervous system is the processing network, the integumentary system protects and covers the body, and the digestive system handles nutrient breakdown and absorption.
