What are the five functions of bones in the skeletal system?

The five primary functions of bones in the skeletal system are: 1) Support, providing a framework for the body; 2) Protection, shielding vital organs such as the heart and brain; 3) Movement, serving as levers that muscles act upon; 4) Mineral storage, particularly for calcium and phosphorus; and 5) Hematopoiesis, the production of blood cells occurring in the bone marrow. Together, these functions are essential for maintaining overall body structure and health.
