Question

Which of the following play a significant role in the maintenance of high osmolarity of cortex interstitial fluid ?

• A. Henle's loop
• B. DCT
• C. PCT
• D. none of these

Answer 1

The correct option is A Henle's loop

A. Henle's loop is a U-shaped that plays a significant role in maintaining high osmolarity of cortex and medullary interstitial fluid.

B. DCT (Distal Convoluted Tubule) is situated in the cortex region of the kidney. In this tubule, conditional resorption of sodium ions, water, and bicarbonate ions takes place.

C. PCT (Proximal Convoluted Tubule) is lined by a layer of brush border cuboidal epithelial cells so that the surface area for reabsorption is increased. This segment helps to maintain the pH and ionic balance of body fluids.

So, the correct answer is 'Henle's loop'.
