The musculoskeletal system provides stability and movement for the body.

• A. Oxygen transport.
• B. Heat production.
• C. Stability and movement.
• D. Hormone regulation.

Answer: (C)

The musculoskeletal system mainly provides stability and movement for the body. It’s made up of bones, joints, and muscles that work together to form a supportive framework and to generate motion. Bones give structure and help maintain posture, while joints allow controlled movement. Muscles attach to bones and contract to pull on them, producing force that enables actions like standing, walking, and lifting. This combination keeps the body stable and enables mobility across different positions and activities.

Oxygen transport is the job of the circulatory and respiratory systems. Heat production is a metabolic byproduct that occurs during activity but isn’t the primary function of the musculoskeletal system, and hormone regulation is the role of the endocrine system.
