During breathing, the diaphragm 'pulls' downwards and the ribcage is also 'pulled' outwards (by the intercostal muscles) - these two movements increase the volume of the chest. This increase in volume creates a lower pressure in the lungs compared to the outside of the body and through diffusion, air is 'sucked' into the lungs.
