This must be the most misunderstood aspect of human anatomy! We have no
direct control of the lungs or diaphram. Only indirectly. We DO have
control of the abdomenal muscles and the chest muscles. Meaning that we
can breath with any combination of abdomen or chest. If we raise the rib
cage, this reduces the pressure in the lung cavity, resulting in the secondary
action of the lungs expanding. If we expand the abdomen, this results in
decreasing the downward pressure against the diaphram, causing the diaphram
to drop, which in turn decreased the pressure in the lung cavity, causing the
lungs to expand. Singers and wind instrument players are taught to breath
with the abdomenal muscles, as this allows more constant, unwavering control
of the air flow.
