Question	Answer	Link
What are the two cells types of the distal tubule and what are their functions?	Principal cells Absorb sodium Excrete potassium and hydrogen Site of action of Aldosterone Intercalated cells ATP driven proton secretion	Link
Where does the collecting duct develop from?	The branched ureteric bud	Link
How is potassium excreted in the distal tubule?	Using the potassium/chloride symporter	Link
By which two methods is H+ secreted?	H+ ATPase H+/K+ ATPase antiporter	Link
