waste products in the blood are filtered out by the kidneys. In the past, kidney failures also led to death because of the buildup of poisonous waste in the blood. Today, however, doctors use dialysis machines to filter wastes out of the blood. Dialysis machines use artificial membranes. Are the membranes and a dialysis machine permeable or selectively permeable? Explain.

Elisa Anthony · Answer 1

The membranes of dialysis machine are semi permeable membrane.

Explanation:

Dailysis is the process of artificial separation of blood from the waste products and excretory substances. This process uses the process of osmotic separation of the blood from the excretory substances by using a fluid which also contains the materials of blood but in small amounts to prepare a osmotic gradient through which when the blood passes, can filter it off. The membrane separating the blood from the fluid is a semi permeable membrane which allows the water to go out along with urea and other excretory products slowly as the blood passes through Dyalysis machine.
