The bones are what make up the frame of the human body. Without bones to hold up together, there would be no frame. They form the skeleton, which supports the soft parts of the body. They actually hold together the entire body. They have a center part called the marrow. The bone marrow contains cells that help produce the red blood cells that transfer oxygen throughout the body. The bones also have many other minerals that keep the body strong.

As strong as the bones are, they do have some bend to them, which we need for protection from bangs and bumps. If we fall hard or are hit by something hard, the bones take a beating, but are protected by the outer tissue surrounding them. However, if the force is too hard, the bones will break, which is how we get fractures. When the body suffers fractures, they are followed by pain, which can be quite severe.
