The removal of wastes from blood using a machine is called hemodialysis. This process involves filtering the blood through a dialyzer to remove waste products and excess fluids, mimicking the function of the kidneys in patients with kidney failure.
Separation of wastes from the blood occurs in the kidneys through a process called filtration. Blood is filtered in the kidneys, where waste products such as urea and excess ions are removed from the blood and sent to the bladder as urine for excretion. This process helps maintain the body's internal environment in balance.
The dialysis machine is the machine that performs dialysis of the blood. Dialysis removes the waste product from the blood by drawing it through a vein in the forearm called the arterio-venous fistula. The blood is pumped into the machine through plastic tubes and then goes through a series of events that cleanses the blood with a saline solution called dialysate. Once the blood has been cleansed, it is returned to the body.
When blood leaves the liver, it contains wastes that need to be filtered or separated out by the kidneys. The kidneys remove waste products from the blood and excrete them as urine.

The two main wastes removed by the urinary system from the blood are urea and creatinine. Urea is a byproduct of protein metabolism, while creatinine is a waste product of muscle metabolism.
