In nephron, water absorption is maximum in

Options

A. Proximal convoluted tubule
B. Loop of Henle
C. Glomerulus
D. Distal convoluted tubule

Answer

### Step-by-Step Solution:

1. **Understanding the Nephron Structure**:
- The nephron is the functional unit of the kidney and consists of several parts: the renal corpuscle, proximal convoluted tubule (PCT), loop of Henle, and distal convoluted tubule (DCT).

2. **Identifying Water Absorption Sites**:
- Water absorption occurs primarily in the nephron, particularly in the PCT, loop of Henle, and DCT.

3. **Analyzing Each Option**:
- **Proximal Convoluted Tubule (PCT)**: This part is responsible for the reabsorption of approximately 90% of the water filtered from the blood. It plays a crucial role in maintaining body hydration.
- **Loop of Henle**: While it does play a role in the concentration of urine and sodium reabsorption, it is not the primary site for maximum water absorption.
- **Glomerulus**: This is where filtration occurs, but it does not absorb water; it merely filters blood.
- **Distal Convoluted Tubule (DCT)**: This part is involved in the reabsorption of minerals and some water, but not to the extent of the PCT.

4. **Conclusion**:
- Based on the analysis, the maximum water absorption in the nephron occurs in the **Proximal Convoluted Tubule (PCT)**.

### Final Answer:
The maximum water absorption in the nephron occurs in the **Proximal Convoluted Tubule (PCT)**.
