The lower boundary of the exosphere is called the exobase. It is also called exopause and 'critical altitude' as this is the altitude where barometric conditions no longer apply. Atmospheric temperature becomes nearly a constant above this altitude.
Sodium â the volatility and solvent mineral: essential to life, all body fluids contain sodium â itâs needed for many biochemical processes including water balance regulation, fluid distribution on either side of the cell walls, muscle contraction and expansion, nerve stimulation and acid-alkaline balance.
Electrolytes are minerals found in your blood, urine and other body fluids that carry an electric charge. These minerals include calcium, potassium, sodium, chloride, phosphorus and magnesium. Electrolytes help with muscle function, as well as the maintenance of fluid balance and your body's pH.
