Answer:
What Is Hemodialysis?
Hemodialysis (pronounced: hee-mo-dye-AL-uh-sis) is a kind of kidney dialysis. It's the one that doctors use most often to take over the kidneys' job of filtering the blood.
Why Do People Need Hemodialysis?
Our kidneys work like a garbage collection system. They clean extra fluid and waste from our blood. These wastes then leave the body as urine (pee).
If the kidneys stop working properly, waste can build up in the blood. That can get dangerous. So people with kidney failure need dialysis to filter out the waste.
How Does it Work?
Hemodialysis uses a machine to pull blood out of the body, filter it, and pump the clean blood back into the body again. The actual filtering happens in a part of the machine called a dialyzer, or artificial kidney.
The dialyzer has two parts. One part is for blood. The other is filled with a cleaning solution called dialysate.
The two parts of the dialyzer are separated by a thin membrane. Blood cells and other important parts of the blood are too big to pass through the membrane. But waste products and extra fluids go through it easily.
The dialysate pulls waste and extra fluids out of the blood, through the membrane, and carries them away. The filtered blood is then pumped back to the body.
Blood flows from the body into the machine and back again through tubes. These tubes are attached to needles in the person's skin. The needles go into a large vein or artery through a vascular access. Doctors need to create this vascular access before dialysis can begin.
