title: [Principles of the structuro-functional organization of the hemomicrocirculatory bed of the intramural nervous plexuses of organs of the gastrointestinal tract of mammals].
abstract: The work deals with one of the least elaborated aspects on the system of microcirculation and is performed, taking into account the functions of histo-hematic and intertissue barriers. For this certain new original investigation methods have been developed, adequate to the problems discussed. The module principle of organization with a distinct functional specialization of the ganglionar and truncal vascular micromodules has been stated. The working principle of each module is based on functional interaction of the intra- and extraneural capillary systems; this is ensured by mechanisms of the blood stream redistribution: by arteriolar, precapillary and prevenular sphincters and by pathways of the shunt blood stream. A high stability of the blood stream in the vascular constructions studied is explained as a possibility of counterstream gas exchange between the arterial and venous blood in the truncal vascular micromodule.
