WebData suggest that AQP1 plays an important role in the physiological accommodation to fetal anaemia, and the level of expression of the water channel aquaporin 1 during cardiac development and in the anaemic fetal sheep heart is determined. Interstitial fluid fluxes are much greater in the fetus than in the adult, and filtration rates are increased over control … WebSummary. Antidiuretic hormone (ADH), also known as vasopressin, is a hormone that regulates water and electrolytes (e.g. sodium) balance. It does so by increasing water reabsorption into the bloodstream by acting on the kidneys nephrons.
