      These are important to maintain our shape. Animals with bones tend to be larger and move around better on land. Those without bones can only really be large if they live in water e.g. jellyfish

      Bones give us structure to maintain our posture. We’d be big blobs without bones. The other important thing they do is protect our vital organs, so the ribcage protects the majority of vital organs like the heart, lungs liver etc, whilst the skull protects the brain.

      They also help the body to move….as they provide support for the muscles in the legs for example…
