title: [3-Dimensional model of the contribution of the vascular and tubular components of the osmoregulatory apparatus of the kidney].
abstract: The method of preparing consecutive series of the reconstruction models of vascular and tubular components of the countercurrent renal system being formed was used to examine their structural organization and spatial interrelations during the prenatal period of rabbit ontogenesis. It was established that the structural and functional unit of the renal osmoregulatory apparatus is represented by a cone-like bundle of tubular formations (the collecting tubule, ascending and descending portions of Henle's loops, vessels) where the central place is occupied by the collecting tubule around which three homogeneous looped tubules of Henle are arranged in a definite manner, the later tubules communicating with the collecting tubule. The presence of the three Henle's loops is accounted for by the fact that each generation of Wolf's duct diverticulum derivatives gives rise to three new populations at whose blind ampullar end there takes place the formation of nephrons.
