  2. Plasma osmolality - Wikipedia

    en.wikipedia.org/wiki/Plasma_Osmolality

    In contrast, osmolality is independent of temperature and pressure. For a given solution, osmolarity is slightly less than osmolality, because the total solvent weight (the divisor used for osmolality) excludes the weight of any solutes, whereas the total solution volume (used for osmolarity) includes solute content. Otherwise, one litre of ...

  3. Osmotic concentration - Wikipedia

    en.wikipedia.org/wiki/Osmotic_concentration

    In simpler terms, osmolality is an expression of solute osmotic concentration per mass of solvent, whereas osmolarity is per volume of solution (thus the conversion by multiplying with the mass density of solvent in solution (kg solvent/litre solution).

  4. Urine osmolality - Wikipedia

    en.wikipedia.org/wiki/Urine_osmolality

    Urine osmolality is a measure of urine concentration, [1] in which large values indicate concentrated urine and small values indicate diluted urine. Consumption of water (including water contained in food) affects the osmolality of urine.

    Osmolality, which refers to the concentration of particles in a fluid, affects how well a beverage hydrates explains Braddock. "Research suggests that beverages with higher osmolality than water, ...

  6. Osmol gap - Wikipedia

    en.wikipedia.org/wiki/Osmol_gap

    The calculated osmolality is then subtracted from the measured osmolality to provide the osmol gap, or the difference between these two values. If this gap falls within an acceptable range,(<10) then it is assumed that sodium, glucose, BUN are indeed the major dissolved ions and molecules in the serum.

  7. Freezing point depression osmometer - Wikipedia

    en.wikipedia.org/wiki/Freezing_point_depression...

    Osmometry is widely used in pharmaceuticals, quality control laboratories, and clinical chemistry to measure the osmolality in aqueous solutions accurately. It is commonly used in medical clinics to assist with various pharmaceutical practices, [10] including the development of lens care solutions and eye drops.

  8. Osmosis - Wikipedia

    en.wikipedia.org/wiki/Osmosis

    The process of osmosis over a semipermeable membrane.The blue dots represent particles driving the osmotic gradient. Osmosis (/ ɒ z ˈ m oʊ s ɪ s /, US also / ɒ s-/) [1] is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a region of high water potential (region of lower solute concentration) to a region of low water potential ...

  9. Osmoregulation - Wikipedia

    en.wikipedia.org/wiki/Osmoregulation

    Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated.
