Quizplus · Accepted Answer

The formation of urine begins in the nephron (3) where the blood undergoes filtration, secretion, and reabsorption processes. The urine then enters the collecting duct (6) which leads to the minor calyx (2) and major calyx (1) where the urine is collected and transported through the ureter (5) to the bladder. Finally, the urine is eliminated from the body through the urethra (4). Therefore, the correct sequence is 3-6-2-1-5-4, which corresponds to choice letter B.
