1.Hypotonic solutions have less solutes and more solvent while hypertonic solutions have more solutes and less solvent.
    2.Hypotonic solutions cause the cell to swell because it promotes shifting of water into it while hypertonic solutions cause the cell to shrink because it pulls the water out of the cell.
    3.Hypotonic solutions can be used for dehydration and hypernatremia while hypertonic solutions can be used for cases of hemorrhage.
    4.Examples of intravenous hypotonic solutions are 0.45 Na Cl and 0.25 Na Cl while examples of intravenous hypertonic solutions are D5LR and D5 .45 Na Cl.

    tonicity refers to the solute concentration of a solution outside a cell and its effect on cellular fluid volume. the osmolarity of the solution determines the direction of water flow into or out of the cell. in normal body situations, solute concentration within and outside of the cell is usually nearly the same (isotonic).

    isotonic: same osmolarity as the cells (270 – 300 mmol/l). equal solute and water—exact same number of particles in both solutions—no net movement of water. does not change cell volume.

    higher solute concentration surrounding cells pulls water out of the cells. hypertonic: higher osmolarity than cells (> 300 mmol/l). greater solute, less water—water moves out of cells. the cell will shrink.

    lower solute concentration surrounding cells causes water to move into the cells. hypotonic: lower osmolarity than cells (< 270 mmol/l). less solute, more water—water moves into cells. the cell will swell.

    isotonicity. if the concentrations of electrolytes are the same in the cell and surrounding fluid, the situation is balanced (homeostatic). the cell fluid volume remains the same.

    hypertonicity: the cell will shrink (crenation) by loss of its fluid to the surrounding hypertonic environment. high osmotic pressure of surrounding fluid pulls fluid out of the cell.

    hypotonicity. in a hypotonic environment, fluid will enter a cell and cause it to swell and burst. the inside of the cell has higher osmotic pressure than the surrounding fluid, so fluid is drawn into the cell.

    both hypertonicity and hypotonicity in the extracellular fluids will destroy cells.
