Question
Answer
Link
The proximal tubule can be subdivided into two parts. What are these parts called?
- Pars convoluter
- Pars recta (straight part)
Link
To which ion is most transport in the proximal tubule linked?
Sodium
Link
Which transporter found in the basolateral membrane is essential to maintain low intracellular sodium levels?
Sodium/potassium ATPase
Link
Why does the concentration of the tubular fluid remain constant along the tubule despite the reabsorption of ions such as sodium?
Water passively follows the reabsorbed sodium so the concentration remains fairly similar but the volume is reduced
