Pulmonary structure and function were quantitatively investigated over the lifespan of the
Fischer 344 rat by morphometric and physiologic techniques. Male animals 1 week, 6 …

The lung's only known essential function is to provide sufficient alveolar surface to meet the
organism's need for oxygen and elimination of CO2. The importance of the magnitude of …

Introduction (characteristics of the chest wall may be a predominant factor in mammalian
respiratory mechanics. Of particular interest is the relative stiffness and inherent relaxed …

To estimate the numbers and volumes of bronchiolar epithelial cells during lung maturation,
we examined rabbits at three time points, 30 days gestation and 4 and 17 weeks postnatal …

The mean linear intercept (chord) length (L m) is a useful parameter of peripheral lung
structure as it describes the mean free distance in the air spaces. It is often misinterpreted as …

A finite element model, comprising an assemblage of tetrakaidecahedra or truncated
octahedra, is used to represent an alveolar duct unit. The dimensions of the elastin and …

The formation of pulmonary alveoli in mice and rats by subdivision of alveolar saccules that
constitute the newborn's gas-exchange region ends by approximately postnatal day 14 …

Basal lung expansion is an important determinant of alveolar epithelial cell (AEC)
phenotype in the fetus. Because basal lung expansion increases toward term and is …

The numbers of alveolar macrophages (AM) are known to be low in utero and to increase
rapidly after birth. This study analyzed factors related to the appearance of AM in the lungs of …
