Bone Formation

       Just like any part of your body, before we were born they had to develop. This is what happened our bones. The bones just didn't appear out of the blue, they had to form and develop. Before we were born, our bones in our skeleton were made completely out of cartilage. Throughout time, the cartilage was broken down and replaced by actual bone. In order for this newly formed bone to get stronger, bone forming cells called osteoblast (AHS tee oh blasts) have to deposit calcium and phosphorus.

      A healthy bone is always being formed and being reformed. In order for the bone to be reformed, something has to break down it. This is the job of osteoclasts  When these osteoclasts brake down, they release calcium and phosphorus. Then the cycle continues.
