Inner medullary interstitium
WebbThe medullary interstitium is the tissue surrounding the loop of Henle in the renal 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. This hypertonicity, in turn, is created by a an efflux of urea from the ... Webb28 feb. 2003 · 3. Newer in vivo studies have confirmed earlier predictions and indirect evidence indicating that the rate of NaCl transport in the ascending limb of the loop of Henle is the major determinant of medullary ionic hypertonicity. 4. The hypothesis of a ‘washout’ of medullary solutes during increased medullary blood flow (MBF) has been …

WebbThis mechanism help to maintain a concentration gradient in medullary interstitium so human urine is nearly four times concentrated than initial filtrate formed. So, the correct … Webb9 maj 2024 · Then, in the distal collecting duct (deep in the inner medulla) the terminal collecting duct becomes urea-permeable. At this stage, the urea concentration gradient forces some of the urea into the renal medullary interstitium, increasing the interstitial osmolality and helping concentrate the urine in the loop of Henle.

Collecting ducts (CDs) coalesce as they descend the … WebbAs the metanephros develops, the primordial insterstitium differentiates to form the larger inner and outer medullary interstitium and the smaller cortical interstitium. In the inner medulla, the interstitium is involved in growth and branching of the collecting duct.
Webb(i) The proximity between the Henle’s loop and vasa recta, as well as the counter current (formed due to the flowoffiltrate in two limb's of Henle's loop in opposite direction) help in maintaining an increasing osmolarity towards the inner medullary interstitium, i.e., from 300 mOsmoL-1 in the cortex to about 1200 mOsmoL-1 in the inner medulla.
