Renal chloride reabsorption



Renal reabsorption of chloride (Cl-) is a part of renal physiology, in order not to loose too much chloride in the urine.

Overview table

Characteristics of Cl- reabsorption
Characteristic proximal tubule loop of Henle Distal convoluted tubule Collecting duct system
S1 S2 S3 descending limb thin ascending limb thick ascending limb connecting tubule initial collecting tubule cortical collecting ducts medullary collecting ducts
reabsorption (%)
reabsorption (mmoles/day)
Concentration (mM) 115[1] 135[1]
electrical driving force (mV) -3[2] +3[2] +15[2] -5 to +5[2] -40[2]
chemical driving force (mV)
electrochemical driving force (mV) (positive) [3]
apical transport proteins (passively)[3]
  • Na-K-2Cl cotransporter[1]
  • Na-Cl cotransporter[1]
basolateral transport proteins chloride channels
