Studies on the microanatomy of the human lung - abstract

ABSTRACT

New concepts of the microanatomy of the human lung are presented. These are based on recent radiographic, electron-micrographic, and morphological data, particularly that derived from the appearances of fixed inflated dried lungs. It is concluded that the spiral collagen-elastic fibres of the alveolar ducts allow changes in volume without changes in surface area but that the very varied appearances do not allow morphometric calculations yet to be drived from geometric models(AU)
