1. Bones protect internal organs from injury by covering or surrounding them.
2. Your skeleton supports your body weight to help you stand and move.
3. The bones themselves are made of minerals and act as a mineral store for calcium and phosphorous, which can be given up if the body requires the minerals for other functions.
4. Certain bones in the skeleton contain red bone marrow and the bone marrow produces red blood cells, white blood cells and platelets.
