Question

Useful material filtered out in nephric filtrate is mostly reabsorbed in the area of-

• A. (A) Bowman's capsule
• B. (B) Distal convoluted tubule
• C. ( C) Loop of Henle
• D. (D) Proximal convoluted tubule

Answer 1

The correct option is D

(D) Proximal convoluted tubule

The correct Option is (D):

Explanation of correct option:-

1. The water, urea, and other salts like glucose are filtered out in renal tubules.
2. The fluid filtered is called glomerular filtrate or nephric filtrate.

Proximal convoluted tubule(PCT):- PCT is the convoluted part of the nephron nearest the Bowman capsule.

1. The nephric filtrate substances transfer into the proximal convoluted tubule(PCT).
2. PCT is the main site of selective reabsorption of sodium, calcium, glucose, amino acid, etc., from the nephric filtrate.

Explanation of incorrect option:-

Option(A) :

1. The nephron has a cup-shaped bag at its upper end, which is called Bowman’s capsule.

Option(B):

1. DCT is a convoluted part that opens in the collecting tubules.
2. Most of the water from the nephron filtrate is reabsorbed through the wall of DCT and collecting tubules.

Option (C):

1. The loop of Henle is a U-shaped tubular structure present in the nephron.

Final answer:- Useful material filtered out in nephric filtrate is mostly reabsorbed in the area of Proximal convoluted tubule.
