Vasa Recta
my gooch has herpes, and I am tired of these Myaandp questions.
The cortical nephrons,from their name are almost entirely embedded within the cortex of the kidney.They have shortish loops of Henle that do not really extend far into the medulla. By contrast, the juxtamedullary nephrons have longs loops of Henle that do extend far into the medulla.The glomeruli of the juxtamedullary nephrons are typically close to the medulla (which is how these got their name)
They are the nephrons that really fine tune the level of concentration of the urine.

renal artery, segmental arteries, interlobar arteries, arcuate arteries, cortical radiate arteries, afferent arterioles, glomerulus, efferent arteriole, peritubular capillaries, venules, interlobar veins, arcuate veins, interlobar veins, renal vein.
In the nephron loops, particularly in the juxtamedullary nephrons.
Yes, juxta means beside or next to and so the juxtamedullary nephrons are those located at the corticomedullary border.
The glomerus a capillary tuft which receives its blood supply from an afferent arteriole of the renal circulation. Its blood pressure provides the power to force fluids and solutes to be filtered out of the blood into the space made by the Bowman's capsule. The remaining unfiltered blood passes into the narrower efferent arteriole. It then moves into the vasa recta, the collecting capillaries intertwined with the convoluted tubules through the interstitial space where the reabsorbed substances also enter. It then joins with the efferent venules of the other nephrons into the renal vein before rejoining with the main bloodstream.
Loop of Hinle
Juxtamedullary Nephron: renal corpuscles close to the base of renal medulla (long loop of Henle and long thin segments that extends in the inner region of renal pyramid) Coritcal Nephron: renal corpuscles in the outer part of the renal cortex (short loop of Henle and hairpin turn in the thick segment) Intermediate Nephron: renal corpuscles in the mid-region of renal cortex (intermediate lenght loop of Henle)
