Hemodialysis uses the principles of diffusion and ultrafiltration to remove electrolytes, waste products, and excess water from the body. Blood is taken from the patient and pumped into the dialyzer, where a semipermeable membrane allows small molecules to pass through. Hemodialysis removes electrolytes and excess water from the body and works on the principles of diffusion and ultrafiltration.
