Quizplus · Accepted Answer

Peritubular capillaries branch from the efferent arterioles of cortical nephrons, and they are involved in the exchange of substances between the blood and the interstitial fluid of the cortex. Vasa recta branch from the efferent arterioles of juxtamedullary nephrons, and they play a crucial role in the concentration of urine, extending into the medulla and helping in the counter-current exchange mechanism.
