A researcher studies lung compliance and pressure-volume curves for the lung and chest wall in healthy adult patients. He discovers that lung inflation follows a different pressure-volume curve than lung deflation. Which of the following terms best describes this phenomenon?

Summary

The pressure-volume (P-V) curves for the lung and chest wall help to study their mechanical behaviors during respiration, as the chest inflates and deflates. These P-V curves are obtained when a patient breathes in and out of a spirometer.
