Roughly how much filtrate do the glomeruli of both kidneys create in a day?
AAbout 200 liters of filtrate
BAbout 20 liters of filtrate
CAbout 500 liters of filtrate
DAbout 2 liters of filtrate
Answer & Solution
Correct answer: A. About 200 liters of filtrate
1. The glomeruli of both kidneys together produce about 200 liters of filtrate every day.
2. Almost all of that volume is recovered further along the nephron.
3. Less than two liters leaves the body as urine, so the smaller figures describe output rather than filtrate.
