WebThe kidney is directed to excrete or retain sodium via the action of aldosterone, antidiuretic hormone (ADH, or vasopressin), atrial natriuretic peptide (ANP), and other hormones. Abnormal ranges of the fractional excretion of sodium can imply acute tubular necrosis or glomerular dysfunction. Acid-base [ edit] Main article: Acid-base homeostasis WebV2 receptors are G protein coupled receptors - the binding of ADH to this receptor causes a rise in the intracellular levels of cAMP, which activates a protein kinase (protein kinase A), which causes vesicles containing aquaporins (water channels) to fuse with the plasma membrane of collecting duct cells.
