[The cardiac microcirculatory bed based on data from the scanning electron microscopy of corrosion preparations].

The method of scanning electron microscopy of cast preparations was used to study the volumetric interrelations of hemo- and lymph microcirculation bed links as well as specific features of the relief of the wall of the heart vessels in question. The lymphangions were confirmed to be rightfully considered as a morphological unit of the lymph microcirculation bed. The valve-shaped impressions and folds of the relief of a cast of lymph capillaries and postcapillaries were found which shows the ability of the lymph postcapillaries to maintain a one-direction flow of lymph and to change the lumen width for different amounts of the flowing lymph.
