Sodium and Water Disorders\n\nScott J.Gilbert  \nAbstract:The balancing of fluids and electrolytes is a core function of the kidneys.There are redundant mechanismswithin the body to sense the adequacy of organ perfusion and the composition of body fluids aimed at maintaining he-modynamics and protecting an environment for optimal cellular function.Sodium and water are key components of extra-cellular fluid and are regulated in response to end-organ perfusion and serum tonicity.Baroreceptors activate the renin-angiotensin-aldosterone system,sympathetic nervous system,vasopressin,and atrial natriuretic peptide to adjust sodiumhandling to alter extracellular volume.Osmoreceptors affectanti-diuretic hormone release and aquaporin activity in themedullary collecting duct to modify the handling of water.Disordered handling of sodium and/or water may be adaptiveor maladaptive,and understanding the stimuli and responses to clinical scenarios assists clinicians in developing appro-priate treatment strategies.  \n◎ 2024 by the National Kidney Foundation,Inc.All rights are reserved,including those for text and data mining,AItraining,and similar technologies.  \nKey
