Reabsorption of useful substances from glomerular filtrate occurs in :...
The cells lining the proximal convoluted tubule are well adapted for reabsorption of materials from the filtrate. The cells reabsorb entire glucose, amino acids, most of the inorganic ions (Na+, K+, Cl ), much of the water as well as some urea from the filtrate.

Proximal Convoluted Tubule
The proximal convoluted tubule is the site where reabsorption of useful substances from the glomerular filtrate occurs. This process is crucial for maintaining the body's homeostasis by reclaiming important molecules and ions that were filtered out in the initial stages of urine formation.
Process of Reabsorption
- The proximal convoluted tubule is lined with specialized cells that actively transport glucose, amino acids, ions, and water back into the bloodstream.
- These cells contain numerous microvilli on their apical surface, increasing surface area for reabsorption.
- The reabsorption of sodium ions creates an osmotic gradient that leads to the passive reabsorption of water, helping to concentrate the urine.
- Other important substances like bicarbonate ions, potassium ions, and uric acid are also reabsorbed in this segment of the nephron.
Significance of Reabsorption
- Reabsorption in the proximal convoluted tubule helps to prevent the loss of essential molecules needed for normal bodily functions.
- It allows the body to regulate its fluid and electrolyte balance by retaining necessary substances and excreting waste products.
In conclusion, the proximal convoluted tubule plays a crucial role in reabsorbing useful substances from the glomerular filtrate, ensuring that the body maintains its internal equilibrium and functions properly.
