Abstract
By means of transillumination (light pipe and microtransillumination) comparative analyses were carried out in geometry, topography and morphometry of microcirculation between the left atrial muscle and cerebral cortex of the cats using computer analysis. In addition, specific types of capillary distribution (symmetric parallel, symmetric antiparallel and asymmetric distribution) in these two organs was ascertained from images visualized on films. It was found that capillary diameter, intercapillary distance, total capillary length per tissue volume, total capillary surface area per tissue volume, total capillary volume fraction and capillary tortuosity differed significantly between the two organs. The left atrial muscle had a low degree of capillary tortuosity and both symmetric and asymmetric distributions. The cerebral cortex had a high tortuosity and mostly asymmetric distribution. These parameters were organotypic and related to their roles in tissue oxygen supply.
