Question

Quizplus · Accepted Answer

The correct sequence starts with the afferent arteriole (1) bringing blood to the glomerulus (4), where filtration occurs. The filtrate then moves through the proximal convoluted tubule (2), the loop of Henle (3), the distal convoluted tubule (5), and finally through the collecting duct system (7). The juxtaglomerular apparatus (6) is involved in regulating blood pressure and filtration rate but is not part of the urine flow pathway.
