 Our bodies are supported (hold) by the skeletal
system, which consists of 206 bones that are
connected by tendons to the muscles.
 The skeleton not only helps us move, but it's also
helps to produce blood cells and the storage of
calcium. The teeth are also part of the skeletal system,
but they aren't considered bones.

have the trachea, the diaphragm and the lungs.
