Renal Flashcards
subunits of nephron in order
renal corpuscle, PCT, loop of Henle, DCT, collecting duct
what cells produce renin
JGA (juxtaglomerular cells)
define macula dena
specialized cells in portion of DCT that senses Na and Cl levels to constrict/dilate afferent and efferent arteriole
what occurs in PCT
reabsorption of most ions
what occurs in thin descending loop of Henle
permeability of water only
what occurs in thick ascending loop of Henle
reabsorption of ions
what occurs in DCT
reabsorption/secretion of ions, secretes H+, creates dilute fluid
what occurs in collecting duct
reabsorption of Na and water; reabsorption and secretion of K; secretion of H+
where does concentration of urine occur
loop of Henle, DCT, and collecting duct
which nephron part does ADH affect
makes DCT and collecting duct more permeable to water allowing for more reabsorption and concentrated urine
where does reabsorption occur in nephron
PCT, collecting duct
where does secretion occur in nephron
PCT, loop, DCT
how do diuretics affect urine
interfere with renal Na reabsorption
