Removal of proximal convolured tuble from the nephron will result in :

Options

A. No change in quality and quantity of urine
B. No urine formation
C. More diluted urine
D. More concentrated urine

Answer

### Step-by-Step Solution:

1. **Understanding the Nephron**: The nephron is the structural and functional unit of the kidney. It plays a crucial role in the excretion of waste and the regulation of water and electrolyte balance in the body.

2. **Identifying the Role of Proximal Convoluted Tubule (PCT)**: The proximal convoluted tubule (PCT) is a part of the nephron where significant reabsorption of water, ions, and nutrients occurs. It contains ciliated epithelium that increases the surface area for reabsorption.

3. **Effect of Removing the PCT**: If the PCT is removed from the nephron, the reabsorption process will be severely impaired. This means that substances, especially water, that would typically be reabsorbed back into the bloodstream will instead remain in the filtrate.

4. **Consequence on Urine Composition**: Without the PCT, the water and other solutes will not be reabsorbed, leading to an increase in the volume of water in the urine. Consequently, the urine will become more diluted.

5. **Conclusion**: Therefore, the removal of the proximal convoluted tubule from the nephron will result in diluted urine due to the lack of reabsorption of water.

### Final Answer:
The removal of the proximal convoluted tubule from the nephron will result in diluted urine due to the lack of reabsorption of water.
