Question

Rearrange the following parts of a nephron based on the flow of fluid inside them.
1. Distal convoluted tubule (DCT)
2. Bowman's capsule
3. Loop of Henle
4. Collecting duct
5. Proximal convoluted tubule (PCT)

• A. 5, 3, 1, 2, 4
• B. 3, 5, 1, 2, 4
• C. 2, 1, 5, 3, 4
• D. 2, 5, 3, 1, 4

Answer 1

The correct option is D 2, 5, 3, 1, 4

$\bullet$ The blood enters into the nephron through Bowman's capsule. Here, primary urine is formed by filtering out the waste and useful materials by the process of ultrafiltration.
$\bullet$ The primary urine moves from the Bowman's capsule to proximal convoluted tubule (PCT) where reabsorption of useful materials takes place.
$\bullet$ From PCT region the urine passes through the loop of Henle to distal convoluted tubule (DCT). Reabsorption of useful materials and secretion of unwanted materials take place in these regions.
$\bullet$ At last, the urine is collected in the collecting duct and then is transferred out of the kidney.
