The arrangement of the microvasculature of the rabbit gallbladder was studied by means of scanning electron microscopy (SEM) of vascular corrosion casts and parallel uncorroded samples, together with correlated light microscopy (LM) observations. The outer layers of the gallbladder wall possess a coarse capillary network supplied by long and straight vessels which also give off numerous smaller twigs for the mucosal layer. Thin richly branched and anastomosing capillaries originate from the mucosal twigs. The mucosal capillaries are arranged in structures having a bowl-like configuration with the convexity facing towards the serosal layer, and the concavity corresponding to the epithelial lacunae seen by SEM of uncorroded samples. These structures were polygonal or irregularly rounded, and limited by vessels arranged in folds. The vessels running in these folds were capillaries and/or venules. The vascular folds corresponded to the epithelial folds demonstrated by SEM and LM of uncorroded samples.
通过对血管铸型和并行未腐蚀样本的扫描电子显微镜（SEM）观察，以及相关的光学显微镜（LM）观察，研究了兔胆囊微血管的排列。胆囊壁外层有一个由长而直的血管供应的粗大毛细血管网，这些血管也为黏膜层发出许多较小的分支。细小的、分支丰富且相互吻合的毛细血管起源于黏膜分支。黏膜毛细血管排列成碗状结构，凸面朝向浆膜层，凹面与未腐蚀样本的扫描电子显微镜观察到的上皮腔隙相对应。这些结构呈多边形或不规则圆形，由排列成褶皱状的血管界定。在这些褶皱中走行的血管是毛细血管和/或小静脉。血管褶皱与未腐蚀样本的扫描电子显微镜和光学显微镜观察到的上皮褶皱相对应。
