Now the metaphysis consists of an important section known as our epiphysical plate and this epiphysical plate is responsible for lengthening and elongating the long bone as the organism as the human actually grows. Now our diaphysis is the long shaft, the long curved shaft that contains our compact bone that basically is responsible for giving our bone its strongness. So basically our long bones are capable of resisting very high tensile and compressive forces and that's exactly why these bones are responsible for supporting our body. In fact, the long bones support the majority of the body's weights. So we have many different types of long bones in our bodies. So let's take a look at the following diagram.
