WebTubular reabsorption is the second major step in urine formation. Most of the reabsorption of solutes necessary for normal body function such as amino acids, glucose, and salts takes place in the proximal part of the tubule. This reabsorption may be active, as in the case of glucose, amino acids, and peptides, whereas water, chloride, and other ... WebSolution. PCT is lined by simple cuboidal brush border epithelium which increases the surface area for reabsorption. Nearly all of the essential nutrients and 70-80 % of water and electrolytes are reabsorbed by this segment. The reabsorption of water in PCT is passive process i.e energy is not required. So, the correct answer is 'Passive 80%'.

Sodium Regulation - Renal Sodium Reabsorption

WebSodium is initially filtered by glomeruli but 60% to 70% of the filtrate is reabsorbed in the proximal tubules. Its reabsorption is primarily affected by aldosterone, along with HCO3-1 and water. Twenty percent to 30% of sodium is reabsorbed into the loop of Henle along with chloride and water. POTASSIUM (K+) WebThis reabsorption occurs in the PCT, loop of Henle, DCT, and the collecting ducts while the majority of secretion occurs in the PCT and DCT ( Table 25.5 and Figure 25.5.1 ).
