WebAug 13, 2024 · Osmolarity of a solution is the number of osmoles of solute per litre of solution. Osmolality is a measure of the number of particles present in solution and is independent of the size or weight of the particles. It can be measured only by use of a property of the solution that is dependent solely on the particle concentration.

WebHigh ADH increases reabsorption of water and produces a low volume of highly concentrated urine; low ADH is associated with a high volume of highly dilute urine. Lowered osmolarity decreases ADH secretion, causing loss of water over salt in the kidney and the blood osmolarity returns toward normal. WebWhat does it mean to have a high osmolarity?
