Which system protects the body and regulates temperature and provides sensation?

• A. Skeletal
• B. Integumentary
• C. Muscular
• D. Endocrine

Answer: (B)

The system responsible for protecting the body, regulating temperature, and providing sensation is the integumentary system. This includes the skin and its associated structures like hair, nails, and glands. The skin forms a protective barrier against injury, microbes, and UV damage. It helps control temperature through sweat production and the regulation of blood flow to the skin: sweating cools the body as the liquid evaporates, and blood vessels can widen to release heat or narrow to conserve it. Sensation comes from a network of nerve endings in the skin that detect touch, pressure, pain, and temperature, sending signals to the brain. While other systems contribute to protection or temperature in broader ways, none combine barrier, temperature regulation, and sensory input as effectively as the integumentary system.
