Learn how hemodialysis removes waste products from the blood when the kidneys fail.

Key points

  • Hemodialysis uses a mechanical kidney, called a dialyzer, to clean the blood when the kidneys can no longer do so.
  • Blood travels to and from the dialyzer through a central venous line or fistula.
  • Hemodialysis can be done at home or in the hospital.
