Renal chloride reabsorption

{{short description|Reabsorption of filtered chloride ions within the kidneys}}

In renal physiology, renal chloride reabsorption refers to the process by which the kidneys, having filtered out waste products from the blood to be excreted as urine, re-absorb chloride ions ({{chem2|Cl-}}) from the waste.
