Protection

• Your bones provide a rigid framework that supports and protects your organs, like the brain, heart and lungs.
  
  

Movement

• Your muscles, their attachments and your bones form the musculoskeletal system. Without it, movement would be impossible.
  
  

Acid Regulation

• The skeleton also absorbs and releases mineral salts to prevent major changes in the acidity of the blood, which can be dangerous to the body.
  
  

Blood Cell Production

• Bone marrow produces red as well as white blood cells.
  
  

Storage of Minerals

• Calcium and phosphorus are stored in your bones when excess amounts are present in the blood and released back into the blood when you need them.
