title: [Microcirculatory bed of the human duodenum].
abstract: In preparations impregnated with silver nitrate (25 corpses of mature persons), the hemomicrocirculatory bed of the intestine wall tunics has been stated to possess a layer-by-layer organization. The most powerful submucosal vascular plexus, formed by branches of the arteries perforating the external tunics of the intestine, supplies with blood all the layers of the intestinal wall and their main working and integrating elements: intestinal and duodenal glands, villi, neural ganglia and trunks of the submucosal and intermuscular plexuses. Summarizing morphometrical criteria for estimating the capillary bed of the tunics of all the anatomical parts and the large duodenal papilla, it is clear that there are specific conditions in microvascularization of the upper part of the organ.
