A large quantity of fluid is filtered everyday by nephrons in the kidneys but only about 1% of it excreted as urine. The remaining 99% of the filtrate

Options

A. is stored in the urinary bladder
B. is reabsorbed into the blood
C. gets collected in the renal pelvis
D. is lost as sweat.

Explanation

**Step-by-Step Solution:**

1. **Understanding Filtration in Nephrons:**
- The kidneys filter a large volume of fluid daily, approximately 180 liters, through the nephrons.
- This filtration process occurs continuously, filtering the entire plasma volume multiple times a day.

2. **Volume of Urine Excreted:**
- Out of the total fluid filtered, only about 1% is excreted as urine. This amounts to roughly 1 to 1.5 liters of urine produced each day.

3. **Calculating the Remaining Filtrate:**
- Since 1% is excreted as urine, the remaining 99% of the filtrate is not lost but instead undergoes further processing.

4. **Reabsorption Process:**
- The 99% of the filtrate is primarily reabsorbed back into the bloodstream.
- This reabsorption occurs in the renal tubules, where essential substances and water are reclaimed.

5. **Conclusion:**
- The correct answer to the question is that the remaining 99% of the filtrate is reabsorbed into the blood.

**Final Answer:**
The remaining 99% of the filtrate is reabsorbed into the blood.
