Bones are hard tissues that form the skeleton in humans and other vertebrates. A bone provides a structure to an organism. Bones protect and support organs and systems, store minerals, and give mobility. In humans, at birth there are more than 270 bones. However, as development takes place some bones fuse together resulting in finally 206 bones in adults. In birds, the skeleton is lightweight to support flying. While in marine mammals and fish, bones are flexible yet strong to support swimming.
