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.
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 ...
Plasma osmolality measures the body's electrolyte–water balance. [1] There are several methods for arriving at this quantity through measurement or calculation. Osmolality and osmolarity are measures that are technically different, but functionally the same for normal use.
Osmosis (also known as Treasure Trove) is a solitaire game played with a deck of 52 playing cards. The object, like many solitaire games, is to put the cards into foundations, although not in numerical order. [1] The name of the game reflects the fact that cards of the same value slowly filter through to successive foundations by osmosis.
Osmotic pressure is an important factor affecting biological cells. [4] Osmoregulation is the homeostasis mechanism of an organism to reach balance in osmotic pressure. Hypertonicity is the presence of a solution that causes cells to shrink. Hypotonicity is the presence of a solution that causes cells to swell.
Cells that have a cell wall tend to be more resistant to osmotic shock because their cell wall enables them to maintain their shape. [4] Although single-celled organisms are more vulnerable to osmotic shock, since they are directly exposed to their environment, cells in large animals such as mammals still suffer these stresses under some ...
