Dialysis tubing is also frequently used as a teaching aid to demonstrate the principles of diffusion, osmosis, Brownian motion and the movement of molecules across a restrictive membrane. For the principles and usage of dialysis in a research setting, see Dialysis (biochemistry) .
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.
We have previously worked with Osmosis to create medical videos under a CC BY SA license. This is a list of the scripts that support some of these videos. This is a list of the scripts that support some of these videos.
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 ...
A super important indicator of tissues not getting enough oxygen due to hypovolemia, is a decreased mixed venous oxygen saturation, or MVO2. MVO2 is the amount of oxygen bound to to hemoglobin in blood coming to the right side of the heart, from the tissues. So it’s like the amount of oxygen left over, or not extracted and used by the tissues.
Osmosis in a U-shaped tube. Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. [1] It is also defined as the measure of the tendency of a solution to take in its pure solvent by osmosis.

Current research also suggests that osmotic stress in cells and tissues may significantly contribute to many human diseases. [6] In eukaryotes, calcium acts as one of the primary regulators of osmotic stress. Intracellular calcium levels rise during hypo-osmotic and hyper-osmotic stresses.
