Which system provides the framework and shape of the body?

• A. Muscular System
• B. Skeletal System
• C. Circulatory System
• D. Endocrine System

Answer: (B)

Think about what gives the body its framework and overall shape. The Skeletal System is responsible for this. It includes bones, cartilage, and joints that form a rigid framework, support posture, protect organs, and define the body's silhouette. Bones act as the main scaffolding, while cartilage shapes and cushions joints, and ligaments stabilize them. Muscles attach to this framework to create movement, but the actual framework comes from the skeletal components. The Circulatory System moves blood, the Endocrine System regulates hormones, and the Muscular System provides force for movement and posture—but none of these establish the body's shape on their own. So, the Skeletal System best provides the framework and shape of the body.
