Muscle and Bone
The human body is the most miraculous machine, containing over 200 moving parts, our bones, operated by more than 600 motors, the muscles. Bone is one of the strongest and lightest materials we know. Yet it is not just a dead framework. Blood vessels thread through the apparently solid bone, and cells inside our ribs manufacture our new blood cells. Between the bones are self lubricating and incredibly tough joints. They pivot the bones as they move under the influence of the muscles.
