Over a long process of evolution, animals developed the complex functions of bones. Not only do bones support the body, they also serve to store and release minerals that the body needs, such as calcium and phosphorus. In addition, bones are constantly being broken down and reformed, and this is controlled by vitamin D and other hormones. Vitamin D works on the cells that create bone to promote bone formation. The bones that these cells build support life itself. Academic supervisor

Script
The entire human body is made of cells, and health is maintained through the continuous process of old cells making way for new cells. Bones are no exception. This film looks into how bones are made up of cells, how they are broken up and how they are reformed. What do the cells that are continuously engaged in bone formation and bone resorption do, and how is balance maintained within the body? Color 17 min.
