There are around 206 ________________ in the adult human body. These bones plus the
connecting tissue make up the _______________ system.
The skeletal system is very important for many reasons. Some bones help _____________ our

be shapeless blobs like a ______________ or an earthworm. Our bones, which are connected by
______________, provide a frame for the rest of the organs, giving us our unique body shape.
The skeletal system also helps us ______________. Muscles, which are attached to bones by
_______________, because the bones to move, which makes our bodies move.

in the blood, some of it becomes bone. If there is not enough calcium, then the bones gives some to
