Approximately how much plasma moves through the kidneys of an adult during a 24-hour period?

The correct answer is approximately 150-180 liters, assuming that the adult in question is average-sized and healthy. During this process, blood enters the kidney through what's called the renal artery. Then, the blood is separated and goes through different arterioles to get to the glomerulus. Here, the blood pressure increases, causing things like water and salts to be filtered out of the blood.
