Volume-Pressure Hysteresis of the Lungs
Recoil due to tissue elastic forces and surface tension are the principal mechanisms which counter balance the inflating transpulmonary pressure of the lungs. The stress-strain properties of the elastic elements and surface tension-area relationships of surfactant are not sufficient to describe the mechanical behavior of the lungs because of the complex arrangement of the alveoli and alveolar ducts (Figure 1.).
