Which body system protects and supports the body; has five functions - provides shape and support, allows movement, protects tissues and organs, stores certain materials, produces blood cells; major organs include the bones?

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

Answer: (A)

This question tests understanding of which body system provides the framework and functions that shape the body, enable movement, protect organs, store materials, and generate blood cells. The skeletal system fits all these roles: bones form the rigid framework that gives the body its shape and support; joints and bones work with muscles to allow movement; the rib cage and skull protect vital organs; bones store minerals such as calcium and phosphorus; and the bone marrow inside certain bones produces blood cells. Other systems don’t encompass all these functions. The integumentary system protects the body and helps regulate temperature but doesn’t provide internal support or generate blood cells. The muscular system enables movement and posture but relies on the skeleton for structure and protection. The nervous system coordinates actions and processes information but isn’t the framework that supports the body or stores minerals or produces most blood cells.
