Osmotic pressure on red blood cells. Osmotic pressure measurement may be used for the determination of molecular weights. Osmotic pressure is an important factor affecting biological cells. [4] Osmoregulation is the homeostasis mechanism of an organism to reach balance in osmotic pressure.
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.
As the osmolyte concentration in fish cells scales linearly with pressure and therefore depth, osmolytes have been used to calculate the maximum depth where a fish can survive. Fish cells reach a maximum concentration of osmolytes at depths of approximately 26,900 feet (8,200 meters), with no fish ever being observed beyond 27,349 feet (8,336 ...
The rate at which fluid is filtered across vascular endothelium (transendothelial filtration) is determined by the sum of two outward forces, capillary pressure and colloid osmotic pressure beneath the endothelial glycocalyx (), and two absorptive forces, plasma protein osmotic pressure and interstitial pressure (). The Starling equation is the ...
The freezing point depression osmometer is an osmometer that is used in determining a solution's osmotic concentration as its osmotically active aspects depress its freezing point. In the past, freezing point osmometry has been used to assess the osmotic strength of colloids and solutions. The osmometer uses the solution's freezing point ...
When the solutes around a cell become more or less concentrated, osmotic pressure causes water to flow into or out of the cell to equilibrate. [8] This osmotic stress inhibits cellular functions that depend on the activity of water in the cell, such as the functioning of its DNA and protein systems and proper assembly of its plasma membrane.
