i) When the ECF solute concentration is lower (hypotonic) than the ICF, water rushes into the cell making it swell and possibly explode.


ii) otential is created by sodium-potassium pumps in the cell membrane, which pump sodium ions out of the cell, into the ECF, in return for potassium ions which enter the cell from the ECF.


iii) Water ater will move into and out of cells and tissues, depending on the. The intracellular fluid (ICF ) is the fluid within cells.Both plasma and the ECF contain high concentrations of sodium and chloride


iv) As cell membranes in general are freely permeable to water, the osmolality of the extracellular fluid (ECF) is approximately equal to that of the intracellular fluid (ICF). Therefore, plasma osmolality is a guide to intracellular osmolality.
