What do bones, joints, and muscles do?

• A. They regulate body temperature.
• B. They provide structure, support, and enable movement.
• C. They process nutrients.
• D. They store energy.

Answer: (B)

The main idea is that bones, joints, and muscles work together to form the body’s framework and to make movement possible. Bones provide shape, support, and protection for organs, and they also store minerals. Joints are where bones meet and allow movement in different directions. Muscles generate the force that moves the bones by contracting and pulling on them across the joints. This collaboration lets you stand, walk, bend, and perform countless movements while also helping with posture and stability. For example, the ribs protect the heart and lungs, and leg bones bear your body’s weight. Other functions listed belong to different body systems—temperature regulation mainly involves the skin and circulatory responses, nutrient processing is the job of the digestive system, and energy storage is primarily in fat tissue and the liver—so they don’t describe the combined role of bones, joints, and muscles.
