By means of intraorganic impregnation of microvessels, it is possible to reveal simultaneously the hemo- and lymphomicrocirculatory beds in the rat and dog hearts and to analyse morphological peculiarities in all parts of the myocardial microcirculatory bed--arterioles, precapillaries, capillaries, postcapillaries, prevenules, venules. It has been demonstrated that the cardiac hemomicrocirculatory bed possesses certain structural-functional units, common for the whole microvascular bed, precapillary sphincters, metarterioles, as well as capillary "sphincters" and arteriolo-venular anastomoses. Lymphatic microvessels of the myocardium are represented by precapillaries and capillaries, the latter varying in their form. The main structural units of the myocardial lymphatic network are reservoir-like microvessels having an essential capicity; at alteration of systole and diastole they perform the role of a specific pump for smaller lymphatic capillaries. Owing to the morphological data obtained, it is possible to interprete anew the mechanisms of the myocardial lymphatic outflow.
通过对微血管进行器官内灌注，能够同时揭示大鼠和犬心脏中的血液微循环床和淋巴微循环床，并分析心肌微循环床各部分（小动脉、毛细血管前括约肌、毛细血管、毛细血管后微静脉、小静脉前支、小静脉）的形态学特征。已经证明，心脏血液微循环床具有某些结构 - 功能单位，这些单位对于整个微血管床是共有的，包括毛细血管前括约肌、后微动脉，以及毛细血管“括约肌”和动静脉吻合。心肌的淋巴管由毛细血管前微静脉和毛细血管组成，后者形态各异。心肌淋巴网络的主要结构单位是具有基本容量的贮器样微血管；在心脏收缩和舒张变化时，它们对较小的淋巴毛细血管起到特定泵的作用。基于所获得的形态学数据，有可能重新解释心肌淋巴引流的机制。
