title: [Intramural vascular system of the large intestine of mammals. A study of the literature].
abstract: From a morphological point of view, too, the summarizing synopsis of the intramural vascular system of the large intestine of mammals shows, that the functional aspect is prominent. As in other studied species the exclusively on the epithelial side existing 'fenestrated endothelium' of the pericryptal and subepithelial capillaries is doubtless the most important structural mark of the large intestinal function, too. Moreover, the direction of the mucosal capillary blood flow informs, that at first the release of the essential substances for the glandular secretion will take place, before epithelial transports concerning the resorption occur. As for the hemodynamic regulatory structures in the wall of the blood-vessels there are obviously differences in their existence depending on the species, respectively they are completely absent such as in the ruminants. Finally, it should be mentioned, that arterio-venous anastomoses could not be detected.
