It functions in renal water reabsorption by building up a high hypertonicity, which draws water out of the thin descending limb of the loop of Henle and the collecting duct system.Hypertonicity, in turn, is created by an efflux of urea from the inner medullary collecting duct.

Mesangial cells are modified smooth muscle cells that lie between the capillaries.
The lumen appears larger in DCT than the PCT lumen because the PCT has a brush border (microvilli). It is also a frequent contaminant of water-damaged houses and of heating ducts.
Many of the tubules in the cortex are swollen, making it somewhat more difficult to distinguish proximal tubules from distal and collecting tubules. Mesangial cells are modified smooth muscle cells that lie between the capillaries.
