The scientific term for bone growth is ossification. This process involves the deposition of minerals, such as calcium and phosphorus, in a framework of collagen fibers to form new bone tissue. Ossification occurs throughout life to maintain bone density and repair bones after injuries.
The substance that makes up the skeleton is called "calcium phosphate," which combines with other minerals and proteins to form bone tissue. Additionally, bone tissue is constantly being broken down and rebuilt in a process called remodeling.
