Movement: The skeleton works with muscles to allow the body to move. The bones act as levers, and the muscles provide the force to move the bones at the joints. Some muscles work as antagonistic pairs. Contracting and relaxing to move the bones in the necessary direction.

Producing blood cells: The bone marrow inside some of the bones produces red and white blood cells, which are essential for carrying oxygen and fighting infection.

Mineral storage: The bones store minerals such as calcium and phosphorus, which are important for bone strength and overall body function.
