Osmoregulation is the process by which a constant osmotic pressure in an organism is maintained. Changes in osmotic pressure are detected by osmoreceptors.
If blood becomes more dilute or more concentrated, osmoreceptors detect this change and feedback to the hypothalamus (supraoptic and paraventricular nuclei and lateral preoptic area). The supraoptic and paraventricular nuclei control the release/suppression of ADH (antidiuretic hormone) from the posterior pituitary[1] which controls the permeability of the collecting duct in the kidney.
