title: [Morphofunctional features of different divisions of the microcirculatory bed of jejunal villi in the white rat].
abstract: By means of injecting the vessels with vegetative peroxidase, scanning electron microscopy of corrosive preparations, biomicroscopy, transmissive electron microscopy and in serial semithin sections, spatial organization of the blood microcirculatory bed of the villus in the white rat jejunum has been studied and identification of various microvascular segments has been made. Increasing dimentions of the villus result only in multiplication of the outflow and inflow pathways of blood, while the number of the marginal capillary-distributers remains unchanged--one along each lateral part of the villus. The cause of this regularity should be sought in certain requirements to orientation of transport processes in the villose stroma and, first of all, in the conditions of the hemato-lymphatic transference at adaptation.
