Answer:
Hemodialysis
Explanation:
Hemodialysis: In the condition of renal failure, the kidneys fail to filter metabolic wastes from the blood, and they fail to produce urine. Harmful wastes build up in the body. Hemodialysis is a procedure that replaces the kidney that does not function. A machine replaces the kidney in order to perform the normal kidney functions. The hemodialysis machine filters the blood. The machine also removes excess water and wastes by means of an artificial filtration membrane. The patient’s blood leaves from a vein through a tube. Then the blood filters slowly through the machine. This process can take several hours before the blood returns to the body. The procedure must be done two or three times each week.
