WebSep 27, 2024 · Filtration results in a tubular fluid that contains not only metabolic waste products, but also useful solutes such as electrolytes, glucose and amino acids. The nephron reabsorbs these essential components. Most of the reabsorption occurs in the proximal convoluted tubule (PCT). Here, 67% of Na +, K +, Cl‾ and water, 85% of HCO 3 … WebProximal tubule. Most of the reabsorption (65%) occurs in the proximal tubule. In the latter part it is favored by an electrochemical driving force, but initially it needs the …

Tubular reabsorption is the process that moves solutes and water out of the filtrate and back into your bloodstream. … WebIf we sampled the fluid at the end of the proximal tubule, where most of the reabsorption has occurred, and we see a value less than 1, then we can deduce that reabsorption of that substance occurred quicker than water. However, as explained above, a value that is still 1 at the end of the proximal tubule (even if the solute was reabsorbed) means
