The endoskeleton of vertebrates have at least three main functions. These are:

1. To support the all parts of the body, including limbs, organs, and the head.

2. To protect vital organisms (IE, the skull protects the brain and the ribcage protects the lungs and the heart.

3. Some bones produce red and/or white blood cells. Blood cells, unlike other cells, do not self replicate, so without the marrow in some of our bones, we wouldn't produce new blood cells and we would soon die.
