Which system provides support and protection for the body, produces blood cells, and stores minerals?

• A. Skeletal System
• B. Digestive System
• C. Nervous System
• D. Immune System

Answer: (A)

The main idea here is recognizing the body’s framework that both supports you and protects organs, while also handling blood cell production and mineral storage. The skeletal system does all of this: bones form the structure that keeps you upright and shapes your body, and the skull and ribcage shield vital organs like the brain, heart, and lungs. Inside certain bones, red bone marrow makes blood cells, including red blood cells that carry oxygen and white blood cells that fight infection. Bones also store minerals such as calcium and phosphorus, releasing them when your body needs them to keep bones strong and to support various functions. The other systems have different jobs—digestion breaks down food and absorbs nutrients, the nervous system sends and processes signals to control the body, and the immune system protects against disease—none of them provide the combination of framework, protection, blood cell production, and mineral storage that the skeletal system does.
