During inspiration, the increase in thoracic volume leads to an increase in pulmonary volume. This increase in pulmonary volume results in a decrease in intra-pulmonary pressure, causing the atmospheric pressure to force air from the outside into the lungs. This process is crucial for breathing and the exchange of gases in the respiratory system.
