In a diagram of the human nephron, the structures are shown in the following order from the renal corpuscle to the point where urine enters the collecting duct: Bowman's capsule, glomerulus, proximal convoluted tubule, loop of Henle (descending limb), loop of Henle (ascending limb), distal convoluted tubule, collecting duct. However, the labels for the two limbs of the loop of Henle have been interchanged. Identify the two structures that are incorrectly labelled and provide the correct sequence of structures in the nephron.

Answer Options

Correct Answer A. The descending limb and ascending limb are interchanged; correct order: Bowman's capsule, glomerulus, proximal convoluted tubule, descending limb, ascending limb, distal convoluted tubule, collecting duct
B. The proximal convoluted tubule and distal convoluted tubule are interchanged; correct order: Bowman's capsule, glomerulus, descending limb, ascending limb, proximal convoluted tubule, distal convoluted tubule, collecting duct
C. The glomerulus and Bowman's capsule are interchanged; correct order: glomerulus, Bowman's capsule, proximal convoluted tubule, descending limb, ascending limb, distal convoluted tubule, collecting duct
D. The descending limb and distal convoluted tubule are interchanged; correct order: Bowman's capsule, glomerulus, proximal convoluted tubule, distal convoluted tubule, ascending limb, descending limb, collecting duct
