Which are functions of the skeletal system?

• A. Hormone production
• B. Support, movement, and mineral storage.
• C. Circulation of blood
• D. Respiration and gas exchange

Answer: (B)

The skeleton acts as the body’s framework and mineral bank. It provides structure and support, offers levers and attachment points for muscles to produce movement, and stores minerals like calcium and phosphorus that the body can draw on as needed. Bone marrow within certain bones also supports blood cell production, adding to its roles. Because of these primary duties, the option listing support, movement, and mineral storage best matches what the skeletal system does. The other options point to functions of the endocrine, circulatory, or respiratory systems rather than the skeleton.
