Features of the blood supply to the wall of the small intestine and its Peyer’s patches
Abstract
Purpose and objectives: 1. To study the blood supply of Peyer’s patches in the norm. 2. To reveal the features of the blood supply of the Peyer’s patches in different sections of the small intestine. The peculiarity of the blood supply to the wall of the small intestine is that it depends on the morphostructure of the wall of this intestine. The distribution of arterial vessels in the submucosa is such that trey are divided into ordinal vessels (1, 2, 3 and 4 orders), which branch into layers and zones of the intestine, end also localized in Peyer’s patches. According to the results of the study , it was reveated that the features of the blood supply to the layers of the wall of the small intestine is that 4 zones of the wall of the intestine differ: mesenteric, antimesenteric (liber) and two lateral zones that differ in morphological and morphometric indicators.
