[Microangioarchitectonics and microtopography of the blood vessels of the human stomach]

The data of previous investigations on general principles of microarchitectonics of the human intraorganic gastric vessels have been checked. Peculiarities of branching and course of the stomach intraorganic vessels, arterio-venous anastomoses, twisted arterioles, sinusoid venules and veins confirm activity and variability of the organ's circulation at microcirculatory level. Certain slight differences in diameters and number of microvessels have been revealed in some anatomical parts of the serous membrane and submucous layer of the stomach. Maximal differences in vessel diameters of the microcirculatory bed and in number of capillaries per 1 mm2 have been revealed in the most active layers of the gastric wall--in muscular and mucous membranes. In the muscular membrane, large vessels and greater number of capillaries have been revealed in the area of the greater curvature and the pylorus. In the serous membrane in the pyloric area and in the area of the smaller curvature, microvessels have smaller diameters and the number of capillaries per square unit is less.
