Osteoporosis Manal Al Mashaleh Osteoporosis Losing density of the bones (thinning of the bones) Understanding Bone Building Like all the cells in the body, bone is constantly changing. Old bone is removed and new bone is formed. This process is done by two types of bone cells: Osteoclasts and Osteoblasts. Osteoclasts remove old bone cells Osteoblasts build new bone cells. When Osteoblasts are more active than Osteoclasts, bones grow. The bones of children grow quickly because their Osteoblasts are more active than their Osteoclasts. Somewhere about the age of 35, the balance begins to shift so osteoclasts become more active than Osteoblasts.
