Question

Maximum amount of water from the glomerular filtrate is reabsorbed in

• A. Proximal convoluted tubule
• B. Distal convoluted tubule
• C. Descending limb of Henle's loop
• D. Ascending limb of Henle's loop

Answer 1

The correct option is A

Proximal convoluted tubule

The correct option is A.

Explanation of correct option:

1. Proximal convoluted tubule helps in 70-80% of reabsorption of water and all essential nutrients.
2. Major reabsorption of water takes place in PCT.

Explanation of incorrect options:

Option B:

Distal convoluted tubule only reabsorbs water during certain conditions.

Option C:

Descending limb of Henle's loop does not take part in reabsorption of water.

Option D:

Reabsorption is minimum in ascending limb of Henle's loop.

Final answer: Maximum amount of water is reabsorbed in PCT.
