Changes

The changes in cell size are quickly corrected by transport processes.  If osmolarity is constant then the volume of each compartment of the body is determined by how many particles of solute are dissolved there.  The relationship is expressed by the following formula:

Concentration = Number of dissolved particles ÷ volume

  '''Concentration = Number of dissolved particles ÷ volume'''

When water is ingested it actually takes a rather long time (30-60mins) before the equilibrium is reset between the ECF and ICF.  This is mainly because it takes time to distribute the water between the organs of the body after it is absorbed.
