Which body system protects and supports the body and has functions such as providing shape, enabling movement, protecting tissues and organs, storing materials, and producing blood cells?

• A. Muscular system
• B. Integumentary system
• C. Skeletal system
• D. Circulatory system

Answer: (C)

The skeleton provides the framework that gives the body its shape and support, and it works with muscles and joints to enable movement. It also protects many tissues and organs—think of the skull safeguarding the brain and the rib cage shielding the heart and lungs. Beyond structure and protection, bones store minerals such as calcium and phosphorus and house marrow where blood cells are produced. In adults, red bone marrow makes red and white blood cells, while yellow marrow stores fat. This combination of support, movement, protection, mineral storage, and blood cell production is why the skeletal system best fits the description. While muscles enable movement and skin offers protection, they don’t provide the rigid framework, mineral storage, or blood cell production that bones do.
