IIRC 95%
Approximately 99% of the filtrate produced by the kidneys is reabsorbed back into the bloodstream. This process occurs primarily in the renal tubules, where substances such as water, electrolytes, and nutrients are reclaimed. Consequently, only about 1% of the filtrate is excreted as urine. This efficient reabsorption is crucial for maintaining fluid and electrolyte balance in the body.
In the proximal tubule, about 65-70% of the filtrate is reabsorbed, mainly through the process of passive and active transport. In the loop of Henle, about 20% is further reabsorbed, while in the distal tubule and collecting duct, the final 10% of filtrate is reabsorbed, with the amount varying depending on the body's needs for water and electrolyte balance.
Glucose in the filtrate is reabsorbed from the nephron back into the bloodstream through the walls of the renal tubules. This process occurs mainly in the proximal convoluted tubule, where glucose transporters actively reabsorb glucose to maintain its concentration in the blood. If there is excess glucose that cannot be reabsorbed, it may be excreted in the urine.
The bowman's capsule collects the filtrate and it enters the tubules. All glucose is reabsorbed immediately into the blood capillaries. As the rest of the filtrate travels through the tubules water and salts needed by the body are reabsorbed into the blood capillaries.yo yo
Transport maximum of the renal proximal tubule
Approximately 99% of filtrate is reabsorbed into the bloodstream in the renal tubules of the kidneys. This high rate of reabsorption allows the body to retain essential nutrients and electrolytes while eliminating waste products.

Glucose enters the filtrate through the glomerular filtration process in the kidneys, but almost all of it gets reabsorbed by the renal tubules. Water freely enters the filtrate during the filtration process, but its reabsorption is tightly regulated by the kidneys based on the body's hydration needs.

Water
In most cases it is reabsorbed. It there is too much, it will be "spilled" into the urine.
the nephrons produce approx 150 litres of glomerular filtrate per day 99% of which is reabsorbed to leave an average of 1.5litres of urine.
Transport maximum of the renal proximal tubule
Glucose that enters the nephron along with the filtrate is normally reabsorbed back into the bloodstream by the renal tubules. This reabsorption process occurs primarily in the proximal convoluted tubule of the nephron through specialized transporters. If there is excess glucose present, it can lead to glycosuria, a condition where glucose is excreted in the urine.
