It is the process of muscle contraction involving the sliding of actin & myosin myofilaments past each other to shorten the length of each sacromere.
This is the passive type of process.
As the diaphragm relaxes, the pleural cavity contracts, which exerts pressure on the lungs. As a consequence, the volume of the lungs reduces and the air is passively pushed out of the lungs. Exhalation is passive, thanks to the elastic properties of the lungs.
