The lungs of five adult Epauleted Fruit-bats (Epomophorus wahlbergi) of mean body weight 96 g were analysed morphometrically. The lung volume per unit body weight was 0.043 cm3/g, the surface area of the tissue barrier (i.e., the effective alveolar surface area) component of the blood-gas pathway per unit body weight was 138 cm2/g, and the surface density of the tissue barrier (surface area of the tissue barrier per unit volume of parenchyma) was 121 mm2/mm3. The harmonic mean thickness of the tissue barrier was between 0.267 and 0.349 micron. The morphometric pulmonary diffusing capacity per unit body weight (DLO2/W) was 0.02 ml O2 per min per mm Hg per g. These values are compared with those of shrews and birds. It is suggested that in bats enlargement of the lungs, small subdivisions of the air spaces, and a thin blood-gas barrier, could be linked with previously reported circulatory adaptations to account for the high oxygen consumption during flight.
对五只平均体重为96克的成年披肩果蝠（Epomophorus wahlbergi）的肺部进行了形态计量学分析。每单位体重的肺容积为0.043立方厘米/克，血气通路的组织屏障（即有效肺泡表面积）部分每单位体重的表面积为138平方厘米/克，组织屏障的表面密度（每单位实质体积的组织屏障表面积）为121平方毫米/立方毫米。组织屏障的调和平均厚度在0.267至0.349微米之间。每单位体重的形态计量学肺扩散容量（DLO2/W）为每分钟每毫米汞柱每克0.02毫升氧气。将这些值与鼩鼱和鸟类的值进行了比较。有人认为，在蝙蝠中，肺部的扩大、气腔的小细分以及薄的血气屏障，可能与先前报道的循环适应有关，以解释飞行期间的高耗氧量。
