How does plasma protein concentration change with excessive NaCl intake? _____

What drives Ca2+ reabsorption in the thick ascending limb (of Henle)?_____

In principal cells, increased ENaC activity (due to aldosterone) causes increased lumen _____ (charge)

How does osmolarity change with excessive NaCl intake? _____

Proximal renal tubular acidosis is characterized by a urine pH _____ 5.5

Through which secondary messenger(s) does the ADH-bound V2 receptor propagate its signal?_____

In response to increased Na+ intake (and ECF volume), there is _____ peritubular capillary oncotic pressure

In the thin descending limb (loop of Henle), tubular fluid becomes progressively _____-osmostic as it descends
