Countercurrent flow in dialysis
WebMay 4, 2024 · In-depth Analysis Countercurrent Flow Geometry In Hemodialysis WebA Hemodialysis. Hemodialysis removes blood and passes it through an extracorporeal circuit and an artificial membrane, with dialysate running in countercurrent flow next to the blood in the membrane. After the blood is filtered through the membrane, it is returned to the body with a reduced quantity of metabolic waste products.
