WebSdum reabsorption subsequently happens at four main sites in the nephron - the proximal tubule, loop of Henle, dstal tubule and collecting duct. Normally, about 99.4% of the filtered sodlum load is resorbed to maintain the con- stancy of total body sodium. The primary sites of this reabsorption are the proximal tu- bule and the loop of Henle. WebReabsorption is a highly specific process that occurs through specific proteins located on the apical membrane of kidney tubule cells. Reabsorption of substances mainly occurs through secondary active transport with Na +. This transport is made possible by the activity of the primary active transporter, the Na + /K + ATPase pump.

WebReabsorption involves active transport of Na(+) and passive reabsorption of Cl(-). The active Na(+) step always involves Na-K-ATPase at the basolateral membrane, but the entry step at luminal membrane varies among tubule segments and among vertebrate classes (except for Na(+)-2Cl(-)-K(+) cotransporter in diluting segment). WebSodium (Na+) Reabsorption Na+ reabsorption occurs along most of the length of the renal tubule The majority of Na+ is reabsorbed in the proximal convoluted tubule Na+ moves across the luminal membrane DOWNits concentration gradient by facilitated diffusion via various types of Na+ transport proteins, & is moved across the basolateral membrane …

WebReabsorption is a highly specific process that occurs through specific proteins located on the apical membrane of kidney tubule cells.
