What is the primary function of the musculoskeletal system?

• A. Respiration
• B. Digestion
• C. Senses
• D. Movement and support

Answer: (D)

The main function is to provide movement and support for the body. Muscles pull on bones across joints, acting as levers to produce motion, while bones form a rigid framework that gives the body shape, supports tissues, and protects internal organs. This system also helps maintain posture and balance, and bones store minerals and house marrow for blood cell production. Respiration, digestion, and sensing come from other body systems—breathing is the job of the respiratory system, digestion of food is handled by the digestive system, and sensory information comes from the nervous system and sense organs.
