Salt is a mineral composed primarily of sodium chloride (NaCl) and is used in food for both preservation and flavor. Sodium ions are needed in small quantities by most living things, as are chlorine ions. Salt is involved in regulating the water content (fluid balance) of the body. Both sodium and chlorine ions are used for electrical signaling ...
When salt is ingested, it is dissolved in the blood as two separate ions – Na + and Cl −. The water potential in blood will decrease due to the increased solutes, and blood osmotic pressure will increase. While the kidney reacts to excrete excess sodium and chloride in the body, water retention causes blood pressure to increase. [10]
Natriuresis is the process of sodium excretion in the urine through the action of the kidneys. [1] It is promoted by ventricular and atrial natriuretic peptides as well as calcitonin, [2] and inhibited by chemicals such as aldosterone.
A bit of salt in the diet is necessary for good health. The seasoning is also a kitchen staple and taste booster, but Americans consume way too much — usually without even picking up a saltshaker.

In renal physiology, renal sodium reabsorption refers to the process by which the kidneys, having filtered out waste products from the blood to be excreted as urine, re-absorb sodium ions (Na +) from the waste. It uses Na-H antiport, Na-glucose symport, sodium ion channels (minor). [1]
The kidneys can also generate dilute urine to balance sodium levels. [8] These electrolytes must be replaced to keep the electrolyte concentrations of the body fluids constant. Hyponatremia, or low sodium, is the most commonly seen type of electrolyte imbalance.
