What is the musculo-skeletal system made up of?
Muscles and bones
Name the 5 functions of the skeleton
- Protection of vital organs

The hard bones of the skeleton protect vital organs from being damaged. For example if a ball hits a person’s chest the ribs protect the heart and lungs
Give two examples of bones that protect vital organs
Cranium protects the brain
Ribs protect the heart and lungs
