Osmoreceptors within the hypothalamus detect and increase in plasma osmolarity. This results in a decrease in ADH release from the posterior pituitary, and hence decrease in water permeability of the collecting duct.
<h3>What is osmoregulation?</h3>
Osmoregulation is that the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to take care of the homeostasis of the organism's water content; that is, it maintains the fluid balance and therefore the concentration of electrolytes to keep the body fluids from becoming too diluted or concentrated.
The tendency of water to move into one solution from another by osmosis is osmotic pressure. The upper the osmotic pressure of a solution, the more water tends to maneuver into it.
<h3>Osmoregulation through kidney :</h3>
Pressure must be exerted on the hypertonic side of a selectively permeable membrane to stop diffusion of water by osmosis from the side containing pure water. Although there could also be hourly and daily variations in osmotic balance, an animal is usually in an osmotic steady state over the long term.
Organisms in aquatic and terrestrial environments must maintain the proper concentration of solutes and amount of water in their body fluids; this involves excretion (getting rid of metabolic nitrogen wastes and other substances such as hormones that would be toxic.

A culture is a way of life of a group of people--the behaviors, beliefs, values, and symbols that they accept, generally without thinking about them, and that are passed along by communication and imitation from one generation to the next. Culture is symbolic communication.
