Having a higher osmotic pressure than a comparison solution; -- of an aqueous solution. Increasing the concentration of dissolved solids increases the osmotic pressure, and thus the tonicity of a solution. Opposite of hypotonic and contrasting with isotonic.
Having an osmotic pressure greater than that of blood plasma, which is approximately that of a 0.2 normal solution of sodium chloride. Cells taken from a medium of normal physiological osmolality and placed in a hypertonic medium will shrink.
refers to the solution in a concentration gradient having the greater concentration ( of solute ). [ A hypertonic solution would have a lesser concentration of solvent but a greater concentration of solute than a hypotonic one.
Referring to an external solution whose solute concentration is high enough to cause water to move out of cells due to osmosis.
A hypertonic solution is one having an osmotic strength greater than that of a cell (~300 mOsm/kg H2O). Such a solution causes water to move out of a cell due to osmosis.
having more solute concentration than another solution, thus exerting greater osmotic pressure than the other solution.
having a higher osmotic pressure than a surrounding fluid or medium
A situation in which the concentration of solutes in a solution is higher than what it contains. For example, a sodium solution of 10 percent would be hypertonic to an animal cell (with a sodium concentration of about 0.9 percent), causing water to leave the cell by osmosis.
Compare with osmotic pressure. Describes a solution which has higher osmotic pressure than some other solution (usually, higher osmotic pressure than cell or body fluids). Freshwater fish die if placed in seawater because the seawater is hypertonic, and causes water to leave the cells in fish's body.
Greater than isotonic concentration.
Hyperosmolar; having a higher concentration of dissolved particles than a reference solution.
Describes any medium with a sufficiently high concentration of solutes to cause water to move out of a cell due to osmosis. (From Greek huper, over.)
having a higher concentration of solutes compared to another solution.
(hi'-pehr-TOHN-ihk) The state of a solution having a greater concentration of dissolved particles than the solution it is compared to.
(of a solution) having a higher osmotic pressure than a comparison solution
having a higher osmolality than the comparison solution.
A solution with an osmotic potential greater than that of living cells, leading to water loss from, shrinkage or plasmolysis of cells in a hypertonic situation. Opposite: hypotonic.
A solution having a high concentration of solute.
Having a greater concentration of solute molecules and a lower concentration of solvent (water) molecules, hence an osmotic pressure greater than that of the solution with which it is compared.
In comparing two solutions, the solution with the higher osmolarity.
higher solute concentration than another fluid
Solution with higher osmotic pressure than plasma (body fluids). Compare isotonic, hypotonic.
Describes a solution containing more ‘particles’ (dissolved solids) than blood plasma.
In biology, a hypertonic cell environment has a higher concentration of solutes than inside the animal or plant cell. Osmosis causes water to flow out of the cell. If enough water is removed in this way, the cytoplasm will have such a small concentration of water that the cell has difficulty functioning.
