#### Part 1: Fill in the blanks
1. bones
2. 206
3. adult, baby
4. shape
5. muscles

#### Part 2: Match
- Rib cage → Heart, Lungs
- Skull → Brain

💡 Explanation:

- The skeleton gives structure and shape to the body.
- Bones provide support and protection (e.g., skull protects the brain, ribs protect heart and lungs).
- Muscles attach to bones and contract to create movement.
- Babies have more bones than adults because some bones (like those in the skull and spine) fuse over time.

This shows how the skeletal and muscular systems work together for movement and protection.

✔ Well done! You’ve learned about the importance of the skeleton!
