Which term describes the skin as a body system?

• A. Dermal system
• B. Integumentary system
• C. Epidermal system
• D. Cutaneous system

Answer: (B)

The skin is part of a body system called the integumentary system. This system includes the skin itself along with structures that extend from it, like hair, nails, and glands, all working together to protect the body, regulate temperature, sense the environment, excrete waste, and synthesize vitamin D. The term dermal or epidermal relates to specific layers of skin (dermis and epidermis) rather than naming the entire system, and cutaneous is an adjective about the skin rather than the official system name. So, the best term that describes skin as a body system is the integumentary system.
