Renal Physiology — Flashcards

Angiotensin II acts directly at the _____ (location) to increase NaHCO3 reabsorption

_____ 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

In the lumen of the collecting duct, _____ and H+ combine to form NH4+

Creatinine clearance slightly _____-estimates GFR because creatinine is moderately secreted by renal tubules

The _____ of the glomerular filtration barrier contains heparan sulfate, which acts as a negative charge barrier

In the _____ of ADH, free-water clearance (CH2O) is positive

Some _____ in the cells of the thick ascending limb diffuse back into the lumen, creating a lumen positive potential difference

In response to increased Na+ delivery (e.g. increased GFR/RPF), the macula densa releases _____, which constricts the afferent arterioles

HCO3- is transported across the basolateral membrane into the blood by:\n1. Proximal tubule: _____\n2. Alpha-intercalated cells: Cl--HCO3- exchange
