Explanation:

Bones are the part of the skeletal system of the body and serve to protect internal organs, serve as the site for the production of RBCs and WBCs as well as store the inorganic salts. Bones do not serve as a site to set the permissible range of blood pressure and body temperature. This function is served by parts of the central nervous system.  

For example, hypothalamus set the body temperature according to the physical conditions. It signals to raise the body temperature during fever.
