Significance of sodium potassium, magnesium and calcium in biological fluids-


  • It is mainly found in blood plasma and also in the interstitial fluid which surrounds the cell.
  • Na^{+} ions help in the transmission of nerve signals also for the regulating water in the plasma membrane.
  • Also for the transport of sugars and amino acids into the cells.


  •  These ions are highly present within cell fluids.
  • Helps in activating many enzymes
  • To produce ATP it oxidises the glucose molecule.
  • Also helps in the transmission of nerve signals.

Magnesium and calcium-

  •  Plays an important role in neuromuscular function (by magnesium), interneuronal transmission, cell membrane integrity and blood coagulation(by calcium) 
  • Mg helps in maintains normal blood circulation in our body.
