Question

In hemodialysis, nitrogenous wastes are cleared from blood through concentration gradient. So when the dialysing fluid and blood attain same amount of nitrogenous waste, the process stops and the blood won't be cleared completely right? Is there any method in dialysis to prevent this?

Answer 1

The fresh fluid is supplied continuously and on the other side, the used fluid containing wastes is also taken out of the hemodialyzer.
