the lungs work by creating a vacuum (pressure gradient) by contracting the diaphragm -- air moves in and flows through the bronchial tubes and into the alveoli. when the diaphragm releases, then air flows outward.
how it differs from a typical pneumatic system is the gas exchange that happens in the alveoli. air that comes in is a mixture of oxygen, nitrogen, co2 and other gases -- but the lungs exchange gases with your bloodstream and so the oxygen is taken into the blood and co2 released, thus you get different gases on exhalation than came in -- otherwise, you'd be dead!
