[Submicroscopic analysis of the microcirculatory system of the pancreas in several vertebrates].
The metabolic link of the microcirculatory system of the exocrinous part of the pancreas studied electron microscopically in the frog, chicken and rat has a general plan of the structure. It consists of capillaries, pericapillary gap and intercellular clefts of glandular cells connected with it. But in the frog and chicken the adventitional layer was found to be absent from the blood capillary wall, the luminal surface of endothelial cells was increased. The width of the basal layer and intercellular clefts in the rat was less than in other objects. The existence of cytoplasmic spiculae of exocrinous pancreocytes in the pancreas of different vertebrates allows to consider them as an element of the exocrinous part microcirculatory system.
