The Connective Tissue Septa in the Foetal Human Lung

Abstract

The adult human lung shows considerable variation in the arrangement and density of connective tissue septa (Reid, 1959). As various authors have considered that in the foetal lung the septa are better developed and more easily seen than in the adult (Sappey, 1874-85; Because of its smallness, the whole of the foetal lung can conveniently be examined, giving an idea of the total distribution of septa, which is described in this paper.
