What system is primarily responsible for protecting the body with skin and appendages?

• A. Musculoskeletal system
• B. Integumentary system
• C. Endocrine system
• D. Circulatory system

Answer: (B)

The integumentary system is primarily responsible for protecting the body with skin and appendages, including hair, nails, and glands. This system acts as a barrier between the body and the external environment, helping to guard against pathogens, chemicals, and physical injuries. It plays a crucial role in maintaining homeostasis by regulating temperature and contributing to sensation through nerve endings within the skin. In contrast, the musculoskeletal system primarily provides support and enables movement through the interaction of bones and muscles. The endocrine system is responsible for hormone production and regulation of various body functions, and the circulatory system operates to transport blood, nutrients, and oxygen throughout the body. While all these systems are integral to overall health and function, the integumentary system is specifically dedicated to protective roles, making it the correct choice in this context.
