A rare genetic disorder leads to impaired urea transport across cell membranes within the nephron. Which region's function would be MOST directly compromised, leading to a significant disruption in the establishment of the medullary concentration gradient?
Proximal Convoluted Tubule
Distal Convoluted Tubule
Thick Ascending Limb of the Loop of Henle
Collecting Duct
Match the following nephron types with the characteristics of their loop of Henle:
| Nephron Type | Loop of Henle Characteristic |
|---|---|
| 1. Cortical Nephron | A. Long loop extending deep into the medulla |
| 2. Juxtamedullary Nephron | B. Short loop primarily in the cortex |
Choose the correct matching:
1-A, 2-B
1-B, 2-A
Both 1-A and 2-A
Both 1-B and 2-B
Each nephron consists of
glomerulus
renal tubules
calyces
A and B
Select the incorrectly matched
proximal convoluted tubule – ionic balance
Henle’s loop – formation of concentrated urine
renal corpuscle – filtration of blood
counter – current mechanism – maintenance of concentration gradient in medulla
