Question
What will happen if instead of 33 vertebrae in our body, we had one single and straight bone?
Solution
A spine is made up of 33 bones, which are called vertebrae. They allow our spines to move, which lets us easily bend them and do other things. We could also say that they make the spine more flexible. Without them, there would be only one straight bone, and we would lose our movement and be stuck in place. We wouldn't be able to sit down or do other things because we would always stand straight up like a pole.
