Question

In the given diagram of Nephron, Identified A, B, C, D and match their function (1 to 4) and select the correct option:
1- Site of ultrafiltration
2- Impermeable to water
3- Reabsorption of glucose/ useful molecules
4- Water reabsorption and regulation of pH of body fluids.

• A. 1-(A), 2-(B), 3-(D), 4-(C)
• B. 1-(A), 2-(B), 3-(C), 4-(D)
• C. 1-(A), 2-(C), 3-(D), 4-(B)
• D. 1-(A), 2-(D), 3-(B), 4-(C)

Hint:

Identify Bowman's capsule, ascending limb, PCT and collecting duct and link each to its function.

Answer 1

The Correct Option is B

Step 1: Identify the parts
A is Bowman's capsule, B is the ascending limb of Henle's loop, C is the proximal convoluted tubule and D is the collecting duct.

Step 2: Match functions
A is the site of ultrafiltration (1).\nB is impermeable to water (2).\nC reabsorbs glucose and useful molecules (3).\nD reabsorbs water and regulates pH (4).

Step 3: Conclusion
The matching is 1-A, 2-B, 3-C, 4-D.

Final Answer:
The correct matching is 1-(A), 2-(B), 3-(C), 4-(D). \[ \boxed{\text{(B) }\text{1-(A), 2-(B), 3-(C), 4-(D)}} \]
