Which body system includes bones and joints?

Which body system includes bones and joints?

• A. Endocrine
• B. Skeletal
• C. Nervous
• D. Circulatory

Answer: (B)

The skeletal system is the body system that includes bones and joints. Bones form the framework of the body, provide structure, protect organs, and store minerals, while joints are the points where two bones meet and allow movement. This combination—rigid bones plus the joints that connect them—defines the skeletal system. The other systems involve different tissues: the endocrine system uses glands and hormones, the nervous system coordinates control through the brain, spinal cord, and nerves, and the circulatory system moves blood through the heart and vessels. So the system that includes both bones and joints is the skeletal system.
