Why does the diaphragm and relax when you breath?
The dipahragm is innervated by the phrenic nerve. This nerve responds to the stimulus sent by the a very particular set of neurons located in the medulla. The main ones are called VRG and DRG. Of these the VRG sends signals to the diaphragm to contract, when the signal is not "on" then the diaphragm relaxes. DRG modulates the depth of breath. There is another group called the pneumotaxic center found in the ponds; this group keeps the VRG in check. If the frequency of respiration becomes too great the pneumotaxic center inhibits depolarization of the VRG for a while in an attempt to restore a "normal" breathing pattern
