Hypertonic solution

Definition

noun

A solution that has higher osmotic pressure (or has more solutes) than another solution to which it is compared.


Supplement

When a cell’s cytoplasm is bathed in a hypertonic solution the water will be drawn out of the cell and into the solution by osmosis. If water molecules continue to diffuse out of the cell, it will cause the cell to shrink.


Compare: hypotonic solution.
See also: solute, solvent.

Tonicity Explanation

... of the osmotic pressure (as defined by the water potential of the two solutions) of two solutions separated by a semipermeable membrane. It is ... tonicness that one solution can have relative to another. The three are hypertonic, hypotonic, and isotonic.

Loop of Henle and Vasa Recta

Sorry I was a little unclear on the first bit! As the solution descends the loop of henle it loses water to the vasa recta, causing its concentration to rise to meet the very hypertonic osmolarity of the interstitial fluids in the renal medulla (so it gets concentrated ...
