_____ syndrome is a renal tubular defect that affects the Na+/K+/2Cl- cotransporter

The _____ and [TF/P]osmolarity ratios both remain at 1 over the course of the PCT

The effects of ECF volume _____ on the Starling forces result in increased fractional reabsorption of isosmotic fluid in the proximal tubule

Atrial natriuretic peptide causes vaso-_____ of afferent arterioles and, to a lesser extent, vaso-constriction of efferent arterioles

In the _____ of the nephron, urea is secreted by simple diffusion

The primary regulation of aldosterone secretion occurs through changes in _____ (via the renin-angiotensin II-aldosterone system) and changes in serum potassium levels
