Microangioarchitecture of the mucosa of the Antrum pyloricum in rabbit was studied by optical and scanning electron microscopy. Passing the lamina muscularis mucosae, arteries of the submucosa reach the lamina propria and branch in to the terminal arteries forming a subglandular network. From these vessels, two capillary nets arise. The first forms a capillary skein around the base of the glands, while the second ascends along the tubuli, moving upwards to the surface along the glandular tubuli. These ascending capillaries also arise directly from the subglandular arterioles of the lamina propria, as well as from capillaries of the basal parts of the glandular tubuli. Subepithelial capillaries form arcuate loops with 2-3 venules or collecting venules, which run into the venous net in the basal region of the lamina propria. Numerous horizontal interconnections exist between the collecting venules but arteriovenous anastomosis in the mucosa was not observed.
采用光学显微镜和扫描电子显微镜对兔幽门窦黏膜的微血管构筑进行了研究。黏膜下动脉穿过黏膜肌层，到达固有层并分支形成终末动脉，构成腺下网络。从这些血管发出两类毛细血管网。第一类在腺底部形成毛细血管网，而第二类沿小管上升，沿腺管向上至表面。这些上行毛细血管也直接起源于固有层的腺下小动脉以及腺管基部的毛细血管。上皮下毛细血管与2 - 3条小静脉或集合小静脉形成弓形袢，后者汇入固有层基部的静脉网。集合小静脉之间存在许多水平连接，但未观察到黏膜中的动静脉吻合。
