Which system provides storage of minerals and blood cell production?

• A. Skeletal
• B. Muscular
• C. Digestive
• D. Endocrine

Answer: (A)

Mineral storage and blood cell production are functions of the skeletal system. Bones store minerals like calcium and phosphorus, releasing them as needed to maintain mineral balance in the body. Inside many bones, bone marrow produces blood cells—red marrow generates red blood cells (and some white blood cells), supporting the body's blood supply. While muscles enable movement, the digestive system handles nutrient breakdown, and the endocrine system regulates hormones, none of which primarily cover mineral storage and blood cell production as the skeletal system does.
