Abstract

Abstract There is considerable physiological evidence that the regional variation in pleural pressure and expansion of the lung is largely determined by gravity. In this paper a method is given based on the technique of finite elements which determines theoretically the mechanical behaviour of a lung-shaped body loaded by its own weight. The results of this theoretical analysis have been compared with actual measurements of alveolar size and pleural pressures in animal lungs.
