<TD>What are the two cells types of the distal tubule and what are their functions?</TD>
<TD><FONT COLOR="#FFFFFF">
* Principal cells
** Absorb sodium
** Excrete potassium and hydrogen
** Site of action of Aldosterone
* Intercalated cells
** ATP driven proton secretion</font></TD>

<TD>Despite urea passively diffusing out of the collecting its concentration actually increases. Why?</TD>
<TD><FONT COLOR="#FFFFFF">
Water follows the urea as it is absorbed</font></TD>
