Question

The reabsorption of 'useful substances' like water, glucose, amino acids, etc. from the glomerular filtrate takes place in

• A. Bowman's capsule
• B. convoluted tubules
• C. afferent arterioles
• D. efferent arterioles

Answer 1

The correct option is B

convoluted tubules

The correct option is B

Explanation for the correct option

1. The reabsorption of 'useful substances' like water, glucose, amino acids, etc. from the glomerular filtrate takes place in convoluted tubules.
2. Reabsorption refers to the absorption of water, glucose, amino acids, salts, and other useful substances from the glomerular filtrate or ultrafiltrate.
3. About 99% of glomerular filtrate is reabsorbed by ‘kidney tubule or nephron’.
4. Different parts of the nephron such as proximal & distal convoluted tubules, Henle's loop play a major role in reabsorption.
5. Most of the reabsorption takes place in proximal convoluted tubules (PCT).

Explanation for the incorrect options

Option A

1. Bowman's capsule receives the glomerular filtrate. It is associated with ultrafiltration.

Option C

1. Afferent arteriole brings blood to the glomerulus for ultrafiltration.

Option C

1. Efferent arteriole takes away blood from the glomerulus after ultrafiltration.
