Scanning electron microscopic (SEM) examination of structures which supply subcapsular and midcortical region postglomerular microcirculation in sheep kidney.
Sheep kidneys were injected with polyester crystic (Dewilux 511-0196) and three dimensional forms of the structure forming the postglomerular microcirculation were examined by scanning electron microscope. During the examination of the afferent and efferent arterioles, a glomerulus with double efferent arterioles were examined and microdiverticular structures were observed in the terminal end of peritubular capillary plexus. It is concluded that these structures widen the surface area of the capillaries as a result of which diffusion across the capillary bed is facilitated.
