The skeleton has numerous essential functions:
Support: It provides a rigid framework that supports the body and maintains its shape.
Protection: It protects vital organs. For example, the skull protects the brain, and the rib cage protects the heart and lungs.
Movement: Bones work with muscles to produce movement. Muscles attach to bones, and when muscles contract, they pull on bones to produce movement.
Mineral Storage: Bones store minerals such as calcium and phosphorus, which are essential for various body functions.
Blood Cell Production: The bone marrow, particularly in long bones, produces red blood cells, white blood cells, and platelets.
Energy Storage: The yellow marrow in bones stores fats, which can be used as an energy source within the body.
