Normally, through contraction and relaxation, the diaphragm does most of the work when it comes to breathing. save when it mud flattened due to the effects of the smoke on the alveoli, muscles in the rib cage and abdomen take over the great deal of the work. Greater reliance on these muscles is a less cost-effective and more tiring way of breathing.
