Final answer:
Bone remodeling is a continuous process in which old bone is resorbed and new bone is formed. About 5 to 10 percent of the skeleton is remodeled annually. This process is important for bone repair and growth.
Step-by-step explanation:
Bone remodeling is a continuous process in which old bone is resorbed by osteoclasts and new bone is formed by osteoblasts. During bone remodeling, bone is destroyed and renewed, allowing for repair and growth. Even without injury or exercise, about 5 to 10 percent of the skeleton is remodeled annually. This process is essential for maintaining bone health and mineral homeostasis in the blood.
