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.
Potassium is a simple mineral that is important for the regulation of our heartbeat. It, along with other electrolytes like sodium and chloride, helps to maintain the proper fluid and electrolyte balance, stimulates muscle contraction, and helps to regulate the acid and base balance in the body.
