How does the skeletal system get energy?

The skeletal system itself does not directly generate energy; rather, it relies on the body's overall energy supply. Bones are living tissues that require energy for maintenance and repair, which they receive through the bloodstream. The energy comes from the metabolism of nutrients, primarily glucose and fatty acids, processed by muscle and other tissues. Additionally, the skeletal system plays a role in storing minerals like calcium, which are vital for various cellular functions that require energy.
