When you take a deep breath, your shoulders go up because your lungs expand. When you breathe through your belly, your belly expands but lungs not much. What are you expanding? Does the air go into your stomach?

Forced inspiration is done using two sets of muscles the external intercostal muscles which are located in between the ribs and pull the ribs outward to increase the area of the thorax. And the abdominal muscles. There is something called the diaphragm that divides the abdomen and thorax. Upon forced inspiration I believe the diaphragm shifts lower pushing the contents of the abdomen downwards.
