Most of the chloride in the body is from salt (NaCl) in the diet. [19] Chloride is part of gastric acid (HCl), which plays a role in absorption of electrolytes, activating enzymes, and killing bacteria. The levels of chloride in the blood can help determine if there are underlying metabolic disorders. [20]
It is called reabsorption (and not absorption) both because these substances have already been absorbed once (particularly in the intestines) and because the body is reclaiming them from a postglomerular fluid stream that is well on its way to becoming urine (that is, they will soon be lost to the urine unless they are reclaimed).
A chloride ion is a structural component of some proteins; for example, it is present in the amylase enzyme. For these roles, chloride is one of the essential dietary mineral (listed by its element name chlorine). Serum chloride levels are mainly regulated by the kidneys through a variety of transporters that are present along the nephron. [19]
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
Fluid balance is an aspect of the homeostasis of organisms in which the amount of water in the organism needs to be controlled, via osmoregulation and behavior, such that the concentrations of electrolytes (salts in solution) in the various body fluids are kept within healthy ranges.
This results in the inhibition of water reabsorption from the kidney tubules, causing high volumes of very dilute urine to be excreted, thus getting rid of the excess water in the body. Urinary water loss, when the body water homeostat is intact, is a compensatory water loss, correcting any water excess in the body.
The body regulates the acidity of the blood by four buffering mechanisms. [citation needed] Bicarbonate buffering system; Intracellular buffering by absorption of hydrogen atoms by various molecules, including proteins, phosphates and carbonate in bone. Respiratory compensation. Hyperventilation will cause more carbon dioxide to be removed from ...
Hyperchloremia is an electrolyte disturbance in which there is an elevated level of chloride ions in the blood. [1] The normal serum range for chloride is 96 to 106 mEq/L, [2] therefore chloride levels at or above 110 mEq/L usually indicate kidney dysfunction as it is a regulator of chloride concentration. [3]
