- Bones provide the structure for our bodies. The adult human skeleton is made up of 206 bones. These include the bones of the skull, spine (vertebrae), ribs, arms and legs.
- Bones are made of connective tissue reinforced with calcium and specialized bone cells. Most bones also contain bone marrow, where blood cells are made.
- Bones work with muscles and joints to hold our body together and support freedom of movement. This is called the musculoskeletal system.
- The skeleton supports and shapes the body and protects delicate internal organs such as the brain, heart and lungs.
- Bones contain most of our body 's calcium supply. The body is constantly building up and breaking down bone tissue as required.
- Heathy bones need a balanced diet, regular weight-bearing exercise and the right levels of various hormones.
