The tonicity of the solution is less than that of the cells. When this occurs, water enters into the blood cells causing them to swell and finally burst, with the liberation of hemoglobin, or water invasion of the body’s cells. If this invasion is beyond the body’s cells, then water intoxication results, with convulsions and edema. See similar questions...
