Kidney medullary interstitium

The medullary interstitium is the tissue surrounding the loop of Henle in the medulla. 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 … Meer weergeven The renal medulla is the innermost part of the kidney. The renal medulla is split up into a number of sections, known as the renal pyramids. Blood enters into the kidney via the renal artery, which then splits up to … Meer weergeven Renal pyramids (or malpighian pyramids or Malpighi's pyramids named after Marcello Malpighi, a seventeenth-century anatomist) are cone-shaped tissues of the kidney.

When the filtrate runs in two different directions in the two arms of Henle’s loop, this is known as countercurrent. The vasa recta, which is tightly linked to these two limbs, works in two directions as well.

WebWater abstraction along the early part of the thin descending limb (tDL) is driven by the high osmolarity (at least half due to urea) present in the medullary interstitium. In the deep nephrons, water reabsorption increases the tubule fluid osmolarity (up to 1200 mOsm/L) and the Na concentration (up to 300 mEq/L) by the bend of the loop.
