Potassium is the most abundant exchangeable cation in the body. It exists predominantly in
the intracellular fluid at concentrations of 140 to 150 meq/liter and in the extracellular fluid at …

The clinical estimation of potassium balance generally depends onthe level of serum
potassium. Since the extracellular fluid contains only 2 percent of the total body potassium, it …

Potassium homeostasis is regulated both by potassium excretion (primarily by the kidneys
and to a smaller extent by the gut) and by potassium distribution regulated primarily by …

Potassium is the most abundant cation in the intracellular fluid, and maintaining the proper
distribution of potassium across the cell membrane is critical for normal cell function. Long …

In healthy individuals wide variations in potassium intake produce only small changes in
total body potassium con-tent, or in plasma potassium concentration. Typically, ade-quate …

Normal potassium homeostasis is regulated by both renal and extrarenal mechanisms.
Although chronic potassium balance is primarily regulated by the kidneys, acute potassium …

An attempt has been made to integrate new findings relevant to potassium metabolism in
health and disease with previously known facts. Particular emphasis has been placed on the …

Total body potassium is about 50 mEq per kg of body weight, or 3500 mEq in a 70 kg
person. Potassium is by far the most abundant intracellular cation and approximately 98 per …

The potassium in the extracellular fluid compartment represents only about 2% of total body
potassium. However, since the concentration of potas-sium in the extracellular fluid is a …

Although only 2% of the body potassium is present in the extracellular space, its
concentration is finely regulated by the internal balance, or distribution of potassium …
