Bone tissue is constantly being dissolved and replaced in the body in a process called bone remodeling. Bone cells called osteoclasts begin the process of bone remodeling by dissolving bone, as diagrammed in Figure 9-1. This is called bone resorption.
New bone is then synthesized by bone cells called osteoblasts to replace the resorbed bone. When bone formation exceeds resorption, bone is growing. When bone formation is slower than bone resorption, osteoporosis may result. Ideally, bone formation matches bone resorption in adults
Figure 9-1 The continuous process of bone resorption.
