"WebOsmoregulation is the active homeostatic regulation of the osmotic pressure of the body fluids within organisms. Changes in the osmotic pressure of the blood are detected by osmoreceptors in the hypothalamus. These changes are then relayed to the control centre, which is also in the hypothalamus. Mammals have two kidneys. " - Knochenfische osmoregulation

Kidneys play a very large role in human osmoregulation by regulating the amount of water reabsorbed from glomerular filtrate in kidney tubules, which is controlled by hormones such as antidiuretic hormone (ADH), aldosterone, and angiotensin II. For example, a decrease in water potential is detected by osmoreceptors in the hypothalamus, which stimulates ADH release from the pituitary gland to increase the permeability of the walls of the collecting ducts in the kidneys. … WebOsmoregulation is the process of maintaining salt and water balance (osmotic balance) across membranes within the body.
