The hemomicrocirculatory bed in the canine pericardium is presented by arterioles, precapillaries, capillaries, postcapillaries and venules situating in various connective tissue layers of the pericardium. Certain morphological peculiarities of the structure of the hemomicrocirculatory bed links are revealed in various parts of the pericardium. As demonstrate morphometry data, the diameter of all the vessels of the hemomicrocirculatory bed in various parts of the pericardium has no precise differences. There are some fluctuations in the number of the capillaries per 1 mm2 in various parts of the pericardium. Their number is comparatively greater in the area of the vascular porta (transitional fold), in the left lateral, in the ventral and dorsal parts of the pericardium. In these parts of the pericardium the density of the capillaries is increased, the network is especially dense in the area where the pericardial transitional fold passes into the epicardium. In the pericardial microcirculatory blood bed adaptive mechanisms (glomeruli, arteriolo-venular anastomoses, microsphincters) performing regulation of the organ's blood stream, are widely presented.
犬心包的血液微循环床由位于心包各结缔组织层的小动脉、毛细血管前微动脉、毛细血管、毛细血管后微静脉和小静脉组成。在心包的不同部位，揭示了血液微循环床各环节结构的某些形态学特点。形态测量数据表明，心包不同部位血液微循环床所有血管的直径并无确切差异。心包不同部位每1平方毫米的毛细血管数量存在一些波动。在血管门（过渡皱襞）区域、心包左侧、腹侧和背侧，毛细血管数量相对较多。在心包的这些部位，毛细血管密度增加，在心包过渡皱襞与心外膜交界处的区域，网络尤为密集。在心包微循环血床中，广泛存在着执行器官血流调节功能的适应性机制（肾小球、动静脉吻合、微括约肌）。
