Tubular Reabsorption of Sodium Ion: Influence of Factors Other Than Aldosterone and Glomerular Filtration Rate

Abstract

Autonomic Nervous System and Systemic HemodynamicsAlthough changes in renal hemodynamics may influence the reabsorption and excretion of sodium through intrarenal mechanisms, the changes in renal hemodynamics seem most likely to be integrated into the control of extracellular-fluid volume by extra-renal adjustments, such as changes in the autonomic nervous system, systemic hemodynamics or humoral mechanisms. The autonomic nervous system has been shown to be involved in the renal excretion of water. Henry and Gauer¹⁰⁸ demonstrated that left atrial distention results in a water diuresis. The afferent limb of this "volume reflex" seems to involve the parasympathetic nervous system since this . . .
