How Does The Bone Function?

Bone is a specialized connective tissue that makes up, together with cartilage, the skeletal system. The human body is composed of 206 bones that perform three main functions.

1) Mechanical: Support and site of muscle attachment for locomotion

2) Protective: For vital organs and bone marrow

3) Metabolic: Reserve of ions for the entire organism, especially calcium and phosphate. Blood cell formation Storage of inorganic salts

An individual bone is composed of cartilage, fibrous connective tissue, blood and nerve tissue. Most of the bone is made of inorganic salts.
