The skeletal system protects soft organs like the heart and lungs, provides support and structure for the body, and allows for movement. It is made up of bones, including the hips, spine, shoulders, knees, and more. Bones are living tissues that are light yet strong, and contain soft bone marrow where most blood cells are produced. X-rays allow doctors to see inside the body and examine the skeletal system. Babies are born with more bones that fuse together into the 206 bones that make up an adult's skeleton. There are different types of bone fractures, such as clean breaks when the bone splits completely or green stick fractures when the bone cracks only partially.

that are light
and strong.

inside many of the
bones is where most of
the blood cells are
made.

How do we know what our bodies look like?

7. Babies have 300 bones which grow and fuse
together to form the 206 bone of adults.

When the bone has
broken into two
bones.

fracture
When the bone cracks
on one side only, not
all the way through.
