The diaphragm functions in breathing. During inhalation, the diaphragm contracts, thus enlarging the thoracic cavity (the external intercostal muscles also participate in this enlargement). This reduces intra-thoracic pressure: In other words, enlarging the cavity creates suction that draws air into the lungs. The structure is a blob below your lungs which helps you breathe.-Wikipedia+ own knowledge
