Dictionary » O » Osmoregulation




The process of regulating water potential in order to keep fluid and electrolyte balance within a cell or organism relative to the surrounding.


In biology, osmoregulation is important to organisms to keep a constant, optimal osmotic pressure within the body or cell. It is the way by which an organism maintains suitable concentration of solutes and amount of water in the body fluids. An example employed by organisms is excretion (such as getting rid of metabolic wastes and other substances toxic to the body when they are in large amounts).

... to ensure that the fish doesn't swell / shrink? If I understand it correctly, using regular salinity would be stupid as live fish is on constant osmoregulation because of osmosis (I am going to add the AFP to this solventand soak the fish in it for several minutes) If this method idea I am proposing ...

Liver and Kidney Evolution! Please Help!

... to say about comparative organ sizes. The only data we have is weight. I'm not sure how this can speak to nephron anatomy if it does at all (for osmoregulation and the like). Any help is greatly appreciated! Many thanks!
