Skeletons | Science Trek

Without a skeleton, we would be a heap of skin and muscles. A skeleton gives shape and form to the bodies of vertebrate animals. The set of bones known as vertebrae make up the spine, and others such as ribs and skull protect the major organs. Bones are actually living tissue, and the center of the bone, or marrow, is where your blood is created. Find out more about your bones.
