Morphological characteristics of comparative-anatomical formation of extra-organic and organic arteries and microcirculatory bed architectonics in duodenum of 312 certain representatives of all classes of vertebrates was given. It was shown that two groups of vessels qualitatively different in form and type of branching formed in the process of historical development: arteries with magistral-arcuate form of branching of non-anastomosing type and that with magistral-annular form of branching. The appearance of arterio-venular anastomosis type junctions in latter ones between one side of the intestine and veins of the opposite side provides the phenomenon of bilateral non-capillary countercurrent organic circulation. Microcirculatory bed of part of the villi completely lacked capillaries, while arterioles were connected with venules expertionally by arterio-venular anastomoses.
给出了312种各类脊椎动物十二指肠中器官外动脉和器官内动脉比较解剖结构形成的形态学特征以及微循环床的构筑学。结果表明，在历史发展过程中形成了两组在分支形式和类型上质的不同的血管：具有非吻合型主弓状分支形式的动脉和具有主环状分支形式的动脉。后者在肠的一侧与另一侧的静脉之间出现动静脉吻合型连接，产生了双侧非毛细血管逆流性有机循环现象。部分绒毛的微循环床完全没有毛细血管，而小动脉仅通过动静脉吻合与小静脉相连。
