Tonicity

  • Stewart M. Brooks

Abstract

Solutions which have the same osmotic pressure as the plasma are isotonic. Those with a lower osmotic pressure are said to be hypotonic, and those with a higher osmotic pressure, hypertonic. (Only in isotonic solutions do cells retain their shape.) Tonicity depends upon the number of particles or osmols of solute; that is to say, solutions containing the same number of osmols are isotonic.
