What are the general function of electrolytes? - Answer:
Controls osmosis of water, regulate bodily secretions, maintains
acid-base balance, carries the electric currents for graded and
action potentials, and serves as cofactors for enzymatic activities
What is natriuresis? - Answer: Increased excretion of sodium by
