[On lymphatic postcapillary].
V.V. Kupriyanov (1969) has described a new structural element within the initial segment of lymphatic bed which was given a name of "lymphatic postcapillary". According to the author, the only reliable distinction of lymphatic postcapillary from capillary is the presence of the valve formed by the folds consisting of the endothelial cells. We believe that the formation of the valve is possible only with the participation of connective tissue elements. Therefore, the protrusion of endothelial cells into the lumen of lymphatic capillary could not be considered as a criterion for the descroption of a new structural element called lymphatic postcapillary.
