Making an x-ray of our ribs


The ribs, like the skull protect delicate parts of our body. The rib cage makes certain that our heart and lungs wont get injured. The skull keeps our brain safe.
Also we learned that our bones are what make us be able to stand tall and straight. without them, we would look like a lump of playdough or jello. They are like the poles that hold up a tent.
