Question

In the artificial kidneys, the tubes are all with semi-permeable lining. Why?

Answer 1

In artificial kidneys, all tubes are semi-permeable and made of cellophane. These tubes are selectively permeable and allow only certain substances to pass through them. The semi-permeable nature allows only the nitrogenous waste products and water to pass through the tubes and does not allow the blood cells and proteins to pass through it.

Answer 2
