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

How the diaphragm helps the lungs?
Your diaphragm contracts and expands when you breath. When the diaphragm contracts, air rushes into the lungs. When the diaphragm relaxes, air is exhaled.
