The Human Skeleton
O
ne of the most marvelous systems in
the world is the human body. The
many parts of your body work together,
allowing you to walk, run, jump, and play.
Even while you sleep, your body keeps working.
Your skeleton is an important part
of you. It is the framework of the body
and gives the body its shape. As you grow,
your skeleton grows and changes with you.
Your bones grow, and some even fuse
together. By the time you are 1 year
old, your skeleton has about
206 different bones.
