[Spatial organization of the microcirculatory bed and organ-tissue functional elements of the myocardium].

Angioarchitectonics of the microhemocirculatory bed (MHCB) of the myocardium have been studied by means of injection techniques and an original method for elective revealing (silver impregnation). Hearts of healthy persons died accidental deaths, those of intact dogs and rabbits have been investigated. The MHCB structure of the left ventrical myocardium has been followed in details; certain peculiarities on distribution of microvessels have been revealed. They secure principally equal conditions for transport-trophic supply for all cardiomyocytes. The data obtained make it possible to outline a principle structural scheme for the organ-tissue functional elements of the myocardium.
