Final answer:
The procedure of diffusing blood through a membrane to remove wastes is known as dialysis, which replicates the kidney's filtration functions for patients with kidney illnesses.
Step-by-step explanation:
The process of diffusing blood through a membrane to remove wastes and maintain the proper balance is called dialysis. This is a critical medical procedure used by patients with kidney illnesses. During dialysis, a patient's blood is sent through a filter that removes waste products, such as urea, while sparing important cellular components like red blood cells. The clean blood is then returned to the body. Dialysis mimics the kidney's natural filtration process, which in a healthy individual, would remove wastes and excess substances from the bloodstream.
