The osmotic concentration of body fluids has such a great effect on cellular function that it is important to understand the units in which it is measured.
One osmole is 1 mole of dissolved particles. If a solute does not ionize in water, then 1 mole of the solute yields 1 osmole osm of dissolved particles. If a solute does ionize, it yields two or more dissolved particles in solution. A 1 M solution of NaCl, for example, contains 1 mole of sodium ions and 1 mole of chloride ions per liter. Both ions affect osmosis and must be separately counted in a measure of osmotic concentration.
Osmolality is the number of osmoles of solute per kilogram of water, and osmolarity is the number of osmoles per liter of solution. Most clinical calculations are based on osmolarity, since it is easier to measure the volume of a solution than the weight of water it contains.
All body fluids and many clinical solutions are mixtures of many chemicals. The osmolarity of such a solution is the total osmotic concentration of all of its dissolved particles.
Tonicity is the ability of a solution to affect the fluid volume and pressure in a cell. If a solute cannot pass through a plasma membrane, but remains more concentrated on one side of the membrane than on the other, it causes osmosis.
A hypotonic15 solution has a lower concentration of nonpermeating solutes than the intracellular fluid ICF. Cells in a hypotonic solution absorb water, swell, and may burst lyse fig.
Distilled water is the extreme example; given to a person intravenously, it would lyse the blood cells. A hypertonic16 solution is one with a higher concentration of nonpermeating solutes than the ICF. It causes cells to lose water and shrivel cre-nate fig. Such cells may die of torn membranes and cytoplasmic loss. In isotonic17 solutions, the total concentration of nonpermeating solutes is the same as in the ICF—hence, isotonic solutions cause no change in cell volume or shape fig.
It is essential for cells to be in a state of osmotic equilibrium with the fluid around them, and this requires that the extracellular fluid ECF have the same concentration of nonpermeating solutes as the ICF.
Intravenous fluids given to patients are usually isotonic solutions, but hypertonic or hypotonic fluids are given for special purposes.
