- Osmotic definition, the tendency of a fluid, usually water, to pass through a semipermeable membrane into a solution where the solvent concentration is higher, thus equalizing the concentrations of materials on either side of the membrane. See more.

osmosis osmosis. 1. Movement of water through a selectively permeable membrane, e.g. a cell membrane. 2. The movement of solvent molecules through a semipermeable membrane from a dilute solution to a more concentrated solution. 3. Diffusion of a fluid (e.g., water) through a semipermeable membrane.

It means the diffusion of fluids through a membrane. Oxygen is diffused into your blood through the alveoli walls by osmosis. The difference between diffusion generally and osmosis is the permeable membrane. osmosis is a type of diffusion.

hypertonic Having a greater degree of tension. Synonym(s): spastic (1) . 2. Having a greater osmotic pressure than a reference solution, which is ordinarily assumed to be blood plasma or interstitial fluid; more specifically, refers to a fluid in which cells shrink. Synonym(s): hyperisotonic.

- 2). Osmotic Pressure: a). Isotonic: The solute concentration of the outside of the cell is equal to the solute concentration inside of the cells so there is no that results in no net movement of water into and out of the cell.

Osmotic lysis Osmotic lysis occurs in animal cells and certain bacteria. When the cells are in a hypotonic environment, the water tends to move into the cell. When the cell membrane cannot hold the excessive influx of water, the cell membrane ruptures. Osmotic lysis does not occur in plant cells because of the cell wall that contains the turgor pressure. Word origin: osmotic » osmosis + New Latin, from Greek lusis, a loosening. Synonym: cytolysis.

Osmotic concentration Osmotic concentration, formerly known as osmolarity, is the measure of solute concentration, defined as the number of osmoles (Osm) of solute per litre (L) of solution (osmol/L or Osm/L).hus, for every 1 mole of NaCl in solution, there are 2 osmoles of solute particles (i.e., a 1 mol/L NaCl solution is a 2 osmol/L NaCl solution). Both sodium and chloride ions affect the osmotic pressure of the solution. Nonionic compounds do not dissociate, and form only 1 osmole of solute per 1 mole of solute.

Non-deductible traditional IRA For example, if 5% of your non-Roth IRA are non-deductible contributions, then 5% of the conversion amount must be non-deductible contributions, and the rest must come from the deductible contributions, including earnings and rollover contributions.hen you make non-deductible contributions to a traditional IRA, you'll have the basis, the amount of non-deductible contributions, reported on Form 8606. When you convert a part or all of your traditional IRA to a Roth IRA, the conversion amount must contain the non-deductible portion proportionally.

Introduction In an isotonic solution—iso means the same—the extracellular fluid has the same osmolarity as the cell, and there will be no net movement of water into or out of the cell. Hypotonic, hypertonic, and isotonic are relative terms. That is, they describe how one solution compares to another in terms of osmolarity. For instance, if the fluid inside a cell has a higher osmolarity, concentration of solute, than the surrounding fluid, the cell interior is hypertonic to the surrounding fluid, and the surrounding fluid is hypotonic to the cell interior.

Osmolality, Osmolarity and Fluid Homeostasis Osmolarity is an estimation of the osmolar concentration of plasma and is proportional to the number of particles per litre of solution; it is expressed as mmol/L. This is what is used when a calculated value is derived. It is derived from the measured Na+, K+, urea and glucose concentrations.

- For other uses, see Osmosis (disambiguation). Osmosis is the spontaneous net movement of solvent molecules through a semi-permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.

- Oxford University Press. DOI:10.1093/acprof:oso/9780198569961.003.0005. In the marine environment, the vast majority of organisms are osmoconformers, meaning that all of their bodily fluids are in osmotic equilibrium with the surrounding seawater. If the salinity of the seawater should vary due to local precipitation or evaporation, the osmotic concentration of the organism's body fluids vary in concert with the change in environmental salinity.

Osmosis Osmosis is the spontaneous net movement of solvent molecules through a semi-permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.hen a cell is submerged in water, the water molecules pass through the cell membrane from an area of low solute concentration to high solute concentration. For example, if the cell is submerged in saltwater, water molecules move out of the cell.

- Osmosis is the process of movement from a hypotonic solution to a hypertonic solution in order to balance the tonicity out. This creates an equilibrium of solutions, without which life could not survive.

Bison hunting Religion also played a big role in Native American bison hunting. Plains Indians generally believed that successful hunts required certain rituals. To Plains Indians, the buffalo was the most sacred animal, and they felt obligated to treat them with respect.

- A hypertonic solution (pronounced Hī-per-TAWN-ik) is a solution with a higher concentration of solute (dissolved substance) than some other, specified solution (and which therefore has a higher osmotic pressure than the other solution). The solution with the lower concentration is then termed hypotonic.

- Exchange of body fluids regulated by osmotic and/or hydrostatic pressures. Osmotic pressure - pressure resulting from the movement of water through a membrane and against its concentration gradient (i.e. the process of osmosis) Hydrostatic pressure - pressure exerted to counteract the process of osmosis.

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/kg solution).
