question 39 (0.5 points)
the correct order of structures that filtrate (urine) passes through in a nephron is
○ bowmans capsule, proximal convoluted tubule, descending loop of henle,
ascending loop of henle, distal convoluted tubule, collecting duct
○ bowmans capsule, distal convoluted tubule, proximal convoluted tubule,
ascending loop of henle, collecting duct, descending loop of henle
○ bowmans capsule, proximal convoluted tubule, ascending loop of henle,
descending loop of henle, distal convoluted tubule, collecting duct
○ bowmans capsule, distal convoluted tubule, proximal convoluted tubule,
ascending loop of henle, descending loop of henle, collecting duct

Explanation:

To determine the correct order, recall the nephron structure and urine flow: Filtrate starts in Bowman’s capsule. Then it moves to the proximal convoluted tubule, followed by the descending loop of Henle, ascending loop of Henle, distal convoluted tubule, and finally the collecting duct. The first option matches this sequence. Other options have incorrect orders (e.g., mixing proximal/distal tubules or loop orders).

Answer:

A. Bowman's capsule, proximal convoluted tubule, descending loop of Henle, Ascending loop of Henle, Distal convoluted tubule, collecting duct
