Peculiarities of the blood supply of kidney dogs and rabbits in comparison

The trunk of the renal artery, in these animals, in the gate organs is divided dichotomously into two, different in diameter, dorsal and ventral renal arteries. Interlobar arteries depart from the renal arteries, in the amount of 6-7, in the rabbit, the diameter of the interlobar artery is 0.13 ± 0.2 mm, less than in the dog, which form arterial arteries d = 0.1 ± 0.2 mm, in an amount 9-12 pairs involved in radial arteries. The latter go along partitions and form a network of capillaries from loops of various forms, oval or polygonal. In predators, these loops have a wide-leafed, in rabbits, small-mesh plexuses.
