Morphologic Peculiarities of the Renal Cortical Vasculature Connected with Blood Redistribution in the Kidney of the Domestic Pig

The cortical blood vessels from 2 to 8 month old Camborow hybrid pigs and Belgium landrace pigs were studied using histologic and semithin sections as well as corrosion casts and cleared preparations of intravascular injection. It was established that the cortical blood vessels of the porcine kidney possess peculiarities that may regulate the redistribution of blood in the cortex. These peculiarities were found in the interlobular arteries, in the efferent arterioles of midcortical nephrons, in afferent arterioles of juxtamedullar glomeruli, and in the glomerular capillary networks. It was established that the number of renal corpuscles is different in the various zones of the cortex.
