An artificial kidney is a device that removes water and waste metabolites from blood, in one such device, the hollow fiber hemodialyzer, blood flows from an artery through the insides of a bundle of hollow cellulose acetate fibers, and dialyzing fluid, which consists of water and various dissolved salts, flows on the outside of the fibers. Water and waste metabolites-principally urea, creatinine, uric acid, and phosphate ions-pass through the fiber walls into the dialyzing fluid, and the purified blood is returned to a vein. Blood from an artery Dialysate Dialyzing fluid Purified blood to a vein Flow Rate Urea (H₂NCONH2) Concentration Water and Urea Removal Arterial (entering) Blood Venous (exiting) Blood 204.5 mL/min 194.8 mL/min 1.95 mg/mL 1.80 mg/mL What is the rate at which water is removed from the blood (essentially the rate at which the volume of blood is reduced)? mL/min What is the rate at which urea is removed from the blood? i mg/min
