WebReabsorption of water and some key electrolytes are regulated and can be influenced by hormones. Sodium (Na +) is the most abundant ion and most of it is reabsorbed by active transport and then transported to the peritubular capillaries. Because Na + is actively transported out of the tubule, water follows it to even out the osmotic pressure.
WebNa + reabsorption occurs in three ways: (1) by entry into the cell by the Na–H exchanger (NHE3) that is coupled to the reabsorption of on the basolateral membrane by the … 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 … WebMar 24, 2024 · Na + reabsorption occurs passively through epithelial Na+ (eNaC) channels and Chloride (Cl –) ions are reabsorbed in the thin ascending limb through Cl– channels. There is some paracellular movement of Na + and Cl – because of the difference in osmolarity between the tubule and the interstitium. Thick Ascending Limb (TAL)
