IX. On the ultimate distribution of the air-passages, and the formation of the air-cells of the Lungs

Abstract

The opinions of anatomists have been much divided as to the manner in which the bronchial tubes terminate; whether the cells composing a lobule of the lungs have free communication with each other, or whether each cell, without any such communication, receives the inspired air by a single bronchial ramification only. The latter opinion, derived from the results of Reisseissen’s investigations, prevails.
