Renal Physiology — Flashcards

H+ is secreted into the lumen of the early PCT via the _____ exchanger, where it combines with filtered HCO3-, forming H2CO3

_____ renal tubular acidosis is due to a defect in the ability of -intercalated cells to secrete H+

Glucose is reabsorbed in the _____ by Na+/glucose (SGLT) cotransporters

In the inner medullary collecting ducts, urea is reabsorbed by the _____ transporter, which is activated by ADH

Phosphate is primarily reabsorbed in the _____ through Na+-phosphate cotransport

_____ syndrome is a renal tubular defect characterized by a gain of function mutation in the ENaC channel in the collecting duct of the nephron

The _____ mechanism of renal autoregulation states that renal afferent arterioles contract in response to vasoactive substances released by the macula densa

Activation of _____ adrenergic receptors on the juxtaglomerular cells causes increased renin release

When CH2O is _____, urine is iso-osmotic relative to plasma

If Cx _____ GFR, there is net secretion of X
