The diaphragm is one. the other is chest(ribs)
let's do better than that.
There are many more than two.
The diaphragm is inspiratory, its contraction sucks the air in.its antagonist is the abdominal wall - the "abs" - it is expiratory.
there are three sets, one set, the external intercostal muscles lifts the ribs, inspiratory, the inernal intercostal is mostly expiratory
and the transversis thoracis is expiratory. It brings the ribs back down.
Let's not forget the muscles of the neck that raise the clavicle and the upper rib. This brings in a small amount of air.
there is a good article in http://www.yorku.ca/earmstro/journey/respiration.HTML
and another for breathing in sport in http://www.aikiU.org
