Bones are living tissues, just like the kidneys, heart, and other organs of the body. They consist of a hard outer shell and a spongy inner network of tissue that is continually remodeled and rebuilt. Bones constantly undergo a type of breakdown and rebuilding to adapt to new mechanical conditions that arise over time. This process of replacing worn-out bone with new bone is called remodeling.
