Functions of the skeleton

The skeleton has over 200 bones. You should be able to identify the main bones in the body.

You also need to understand the five functions of the skeleton. These are:

1. Protection - the cranium and ribs protect the brain and vital organs in the chest.
2. Shape - gives shape to the body and makes you tall or short.
3. Support - holds your vital organs in place when playing sport. The vertebral column holds the body upright.
4. Movement - muscles are attached to bones, which are jointed. When the muscles contract the bones move.
5. Blood production - red blood cells (to carry oxygen) and white blood cells (to protect against infection) are produced in the bone marrow of some bones.
