This basolateral Na/K ATPase serves as
driving force for Na reabsorbtion

Water then follows the Na from apical to
basolateral side. Driving force for water
reabsorption is osmotic.

Glucose re- absorption is by glucose/Na
symporter. Driving force is also Na gradient.

CCD Na/K ATPase is activated by aldosterone which
causes increased Na reabsorption increased
water reabsorption and increased volume/BP
Preferred path of K secretion
aldosterone
