Osmotic gradient. From The School of Biomedical Sciences Wiki. Jump to: navigation, search. Osmotic Gradient is a pressure caused by water molecules that forces water to move from areas of high water potential to areas of low water potential. peruviana, however, an osmotic gradient sufficient to increase egg capsule weight by 30% was sufficient to open most egg capsules that contained advanced offspring; such osmotic gradients did not cause capsules containing earlier development stages to open.
Englisch: osmotic diuresis. 1 Definition. Als osmotische Diurese bezeichnet man eine vermehrte Wasserausscheidung über die Niere, die durch osmotisch wirksame Substanzen ausgelöst wird. 2 Physiologie. Die physiologische Harnkonzentrierung erfolgt überwiegend auf passivem Weg, indem der Tubulusflüssigkeit per Osmose Flüssigkeit entzogen wird. 18.09.2007 · An osmotic gradient refers to differing particle concentrations on the two sides of the membrane. You can't have an example of a gradient because it isn't a thing. Its a state. Definitions of Osmotic gradient, synonyms, antonyms, derivatives of Osmotic gradient, analogical dictionary of Osmotic gradient English English » English ↔ search: Arabic Bulgarian Chinese Croatian Czech Danish Dutch English Estonian Finnish French German Greek Hebrew Hindi Hungarian Icelandic Indonesian Italian Japanese Korean Latvian Lithuanian Malagasy Norwegian Persian Polish. 06.10.2008 · The difference in osmotic potential between two areas, usually seperated by a membrane. Different substances can alter the osmotic balance of a liquid. For example the osmotic potential of water is usually 0, so there would be no movement whatsoever. If salt was added on 1 side of a semi-permeable membrane however the gradient would be from the fresh water to the salt water as salt.

Free learning resources for students covering all major areas of biology. Osmotic Pressure Definition Osmotic pressure can be thought of as the pressure that would be required to stop water from diffusing through a barrier by osmosis. In other words, it refers to how hard the water would “push” to get through the barrier in order to diffuse to the other side.
Der Gradient ist ein mathematischer Operator, genauer ein Differentialoperator, der auf ein Skalarfeld angewandt werden kann und in diesem Fall ein Vektorfeld liefert, das Gradientenfeld genannt wird. Water will move quickly from the side of the lower osmotic concentration toward the side with the higher osmotic concentration until the osmotic gradient is abolished. Thus, the volume of a compartment reflects the percentage of osmotic solutes in that compartment and the total amount of water available Fig. 2-2.
Osmotic Gradient Definition Freeware AR Gradient ActiveX Control v.1.05 This is just another gradient ActiveX control, with a few features that I have never found in other gradient controls, like the ability of acting as a title bar and moving the form in which it is. osmotic fragility susceptibility of certain erythrocytes to hemolysis when exposed to increasingly hypotonic solutions; seen in some forms of hemolytic anemia and spherocytosis. A test of osmotic fragility is used in diagnosis of some types of hemolytic anemia. osmotic diarrhea diarrhea induced by a nonabsorbable osmotic load. osmotic diarrhea Internal medicine An ↑ in volume and frequency of fecal flow due to ingestion of a poorly absorbable solute–either a carbohydrate or divalent ion or hypertonic material, resulting in a fecal osmolality higher than plasma osmolality; OD may occur in antacid. Osmotic pressure is the energy driving osmosis and is important for living organisms because it allows water and nutrients dissolved in water to pass through cell membranes. Find the definition of Concentration gradient in the largest biology dictionary online. Free biology and life science resources at your fingertips.
In this section, we examine two types of transport phenomena that, at first glance, may seem unrelated: the regulation of cell volume in both plant and animal cells, and the bulk flow of water the movement of water containing dissolved solutes across one or more layers of cells. In humans, for example, water moves from the blood filtrate that. Medullary osmotic gradient. Final concentration of urine in the collecting ducts rely on the medullary osmotic gradient Mechanism. Medullary osmotic gradient is produced by Active sodium transport by thick ascending limb from lumen into interstitium Low blood flow countercurrent mechanism of vasa recta Recycling of urea. Learn how molecules move through a membrane by passive diffusion and how active transport osmosis affects animal and plant cells in National 5 Biology. Osmotic blistering is one of the most common failure modes for coatings in wet service environments, yet it is not a well understood failure mechanism. Osmotic blistering is all too familiar in certain applications, such as industrial marine coatings and linings and gel coats on boats and swimming.

Osmose bezeichnet die Diffusion einer Flüssigkeit durch eine selektiv-permeable Membran entlang eines Konzentrationsgefälles der Lösungsmittel im Bezug auf die gelösten Teilchen. Die Diffusion erfolgt in Richtung der höheren Konzentration. 2 Prinzip. Define osmotic. osmotic synonyms, osmotic pronunciation, osmotic translation, English dictionary definition of osmotic. n. pl. os·mo·ses 1. a. Diffusion of fluid through a semipermeable membrane from a solution with a low solute concentration to a solution with a higher.

You can complete the translation of osmotic gradient given by the English-French Collins dictionary with other dictionaries such as: Wikipedia, Lexilogos, Larousse dictionary, Le Robert, Oxford, Grévisse.
Difference Between Osmotic Pressure and Oncotic Pressure Definition. Osmotic pressure is the pressure needed to stop the net movement of water across a permeable membrane which separates the solvent and solution. Oncotic pressure is the contribution made to total osmolality by colloids. Measured by: Osmotic pressure is measured by osmometer. osmotic pressure definition: Osmotic pressure is the force caused by a solution passing through a semi permeable surface by osmosis, which is equal to the force required to resist the solution from passing back through the surface. noun An example of osmotic.
Define gradient. gradient synonyms, gradient pronunciation, gradient translation, English dictionary definition of gradient. n. Abbr. grad. 1. A rate of inclination; a slope. 2. An ascending or descending part; an incline. 3. Physics The rate at which a physical quantity, such as. 27.03.2001 · This is shown to be sufficient to reverse the oocyte shrinkage into a swelling phase apparently “against” an imposed osmotic gradient. This is to be expected if the osmolyte accumulation is capable of “locally” reversing the imposed osmotic gradient of 10 mOsm. Clearly, the direction of the water flux cannot be taken as an indication of. 6.1 Osmotic Forces & Compartment Volumes Osmosis refers to water flow across a membrane into a region where there is a higher concentration of a solute to which the membrane is impermeable. Water moves because of diffusion down a concentration gradient.
