| Abstract: | In human fetuses 12-20-week-old peculiarities in creation and development of the pancreatic hemo-microcirculatory bed have been studied in connection of its incretory part formation. The vascular glomerulus begins to form on the 12th-14th week as transformation of capillaries of the exocrinic parenchyma into the glomerular capillaries, which, on their getting out of the glomeruli, turn into vessels. The latter participate in formation of the insulo-acinar portal system. Certain structures have been revealed for adaptation of an elevated volume of the blood stream in the glomeruli place, where the glomerular microvessels pass into the acinar anastomoses. The latter perform shunting of the glomerular capillaries with the arteriole, which brings blood, enriched in insular hormones, to distantly situating acinar cells. |
