Quizplus · Accepted Answer

The porous walls of the glomeruli, which are tufts of capillaries in the renal cortex, allow water and small solutes to be filtered out of the blood plasma and into the nephrons. The other structures listed (vasa rectae, loops of Henle, collecting ducts, and juxtaglomerular apparati) are all involved in the process of urine formation, but they do not primarily function in the filtration of blood plasma.
