Answer 1

A large quantity of fluid is filtered every day by the nephrons in the kidneys. Only about 1% of it is excreted as urine. The remaining 99% of the filtrate is reabsorbed into the blood.

Explanation:

When the volume of filtrate created per day (180 L/day) is compared to the volume of urine released (1.5 L), it appears that 99% of the filtrate must be reabsorbed by the renal tubules via a process known as reabsorption.
