The distal convoluted tubule is only found in the cortex. See the diagram. Blood flows directly from interlobar arteries into arcuate arteries. Blood flows directly from interlobular arteries into arcuate arteries. Blood flows directly from the vasa recta into afferent arterioles.
Blood flows directly from efferent arterioles into afferent arterioles.
Blood flows directly from the peritubular capillary plexus into arcuate arteries. A. See the diagram. Medullary pyramids reflect the lobulation of the kidney. Thin segments of the loop of Henle are characteristically found in medullary rays. Juxtamedullary nephrons with long thin limbs in their loops of Henle are important for the production of hypertonic urine.
