"Considering the distribution of the body water between the intracellular and extracellular compartments and the chemical composition of the compartments, one can deduce that most of the body’s Na+ is in the extracellular fluid, whereas most of the K+ is in the intracellular fluid. There are ~60 mmoles of Na+ per kg body mass: ~10% in the intracellular fluid. 50-60% in the extracellular fluid. and the rest in bone...Even small shifts of K+ from the intracellular to the extracellular compartment thus may lead to large changes in the extracellular [K+] concentration, [K+]e, and vice versa for Na+." |
