The phrenic nerves are responsible for innervating the diaphragm, the primary muscle involved in breathing. After inspiration, when the diaphragm contracts to facilitate air intake, it is essential for it to also manage elastic recoil, which helps in expelling air from the lungs during expiration.

The continued stimulation of the diaphragm by the phrenic nerves ensures that the muscle can efficiently transition from an active state during inspiration to assist in the passive process of expiration, responding appropriately to the changes in intrathoracic pressure. This is vital in maintaining effective ventilation, as the diaphragm's ability to relax and return to its original position contributes to the elastic recoil mechanism of the lungs.

Other nerve types, such as vagus and intercostal nerves, play roles in respiratory function but are not the primary drivers for the diaphragm's movement in the context of managing elastic recoil. The vagus nerves primarily provide sensory information and regulate autonomic functions, while the intercostal nerves are involved mainly in activating the muscles between the ribs during breathing but do not directly stimulate the diaphragm in the same way.
