Answer:
All of the above are functions of the skeletal system
Explanation:
The skeletal system is composed of bones, cartilage, ligaments, and skeleton.
The body system has multiple functions;
Protection; example is the skull that protects the brain and the rib cage that protects the lungs and heart
Storage of inorganic molecules such as calcium and phosphates in bones – that are used in ossification- that can be reabsorbed when the concentration of these elements in blood goes down.
The bone also act as a pivot on which muscles act on to offer locomotion. The skeleton also offers a support structure on which the body takes its shape
The other function of the skeletal system is the production of blood cells that are developed in the bone marrows.
