The body’s skeleton forms and grows to its adult size in a process called modeling. It then completely regenerates — or remodels — itself about every 10 years.
Do skeletons support the body?
Bones provide a rigid framework, known as the skeleton, that support and protect the soft organs of the body. The skeleton supports the body against the pull of gravity. The large bones of the lower limbs support the trunk when standing. The skeleton also protects the soft body parts.
What are the 4 main parts of the skeletal system?

What is the function of the skeleton?
Like the steel framework of a building, the functions of the skeleton and the bones is to provide rigidity, which gives the body shape and supports the weight of the muscles and organs. Without this structure, the body would collapse in on itself, compressing the lungs, heart and other organs–impairing their function.
