Sodium homeostasis

Sodium balance is so well controlled by homeostatic mechanisms in normal individuals that little attention is usually given to sodium intake. Where goes sodium, water soon follows whether by osmosis or bolus flows. All living organism have tor regulate sodium and water in order to remain in homeostatic and thrive.

In response to acute salt loads (meals, snacks) sodium blood is maintained constantly the triplet of banking some in the huge extracellular fluid reservoir, withdrawing water thereform and urinating the excess remnant.

Practically all ingested sodium is absorbed and the kidney is responsible for maintaining sodium homeostasis. Normal plasma levels for sodium adults range from 136 to 146 mEg/L and this balance is normally maintained by an average dietary intake of 90 to 250 mEq per day. Sodium excretion tends to reflect sodium intake, and on an average diet, urine sodium excretion will range between 80 and 180 mEq per day.
