What Is the Proximal Convoluted Tubule?
Proximal tubule: The proximal tubule can be divided into straight and curved parts. Its curved part, also known as the proximal curved tubule, is located in the cortical labyrinth and is highly curved near the renal corpuscle.

- Proximal tubule: The proximal tubule can be divided into straight and curved parts. Its curved part, also known as the proximal curved tubule, is located in the cortical labyrinth and is highly curved near the renal corpuscle.
- Proximal tubule cells secrete drugs from the plasma into the renal tubules in an active manner.
- Many drugs have an affinity for the active transporter on the proximal tubule that is significantly higher than that for plasma proteins. Therefore, unlike glomerular filtration, the rate of drug secretion by the tubules is not affected by plasma protein binding.
- Normally, the reabsorption rate of the proximal tubule increases with increasing glomerular filtration rate.
