The juxtamedullary nephrons (~15%) are responsible mainly for:
APerforming the bulk of routine filtration
BSecreting H+ ions into urine to acidify
CProducing the hormones ADH and aldosterone
DSetting up the medullary concentration gradient
Answer & Solution
Correct answer: D. Setting up the medullary concentration gradient
Juxtamedullary nephrons have LONG Loops of Henle that dive deep into medulla. Via counter-current multiplier, they set up the hyperosmotic gradient enabling concentrated urine. Cortical nephrons (85%) handle most routine work.
