<TD>The proximal tubule can be subdivided into two parts. What are these parts called?</TD>
<TD>
<FONT COLOR="#FFFFFF">
* Pars convoluter
* Pars recta (straight part)</FONT></TD>

<TD>To which ion is most transport in the proximal tubule linked?</TD>
<TD>
<FONT COLOR="#FFFFFF">
Sodium</FONT></TD>

<TD>Which transporter found in the basolateral membrane is essential to maintain low intracellular sodium levels?</TD>
<TD>
<FONT COLOR="#FFFFFF">
Sodium/potassium ATPase</FONT></TD>

<TR>
<TD>Why does the concentration of the tubular fluid remain constant along the tubule despite the reabsorption of ions such as sodium?</TD>
<TD>
<FONT COLOR="#FFFFFF">
Water passively follows the reabsorbed sodium so the concentration remains fairly similar but the volume is reduced</FONT></TD>
