Q

Why are the intercalated discs important? Where are they?

A

Intercalated cells have apical microvilli and contain many mitochondria.
They engage in K+ and HCO3- secretion out of and H+ secretion into the collecting duct.

Q

As Water descendss in the Loop, what happens and why?

A

Becomes Saltier

Because its permeable to H2O BUT NOT Salt Water will be diffusing … Water Follows Salt!
