    • Persons blood leaves body
    • Blood gets thinned to prevent clotting
    • Enters dialysis machine
    • Blood flows between partially permeable membrance
    • Other side of membrane is dialysis fluid
    • Fluid contains same conc glucose and mineral ions as the blood therefore no net movemnet of g and min ions out of blood
    • Excess salt and urea moves out of body by diffusion along conc grad
    • In machine: one side dialysis fluid goes in and other side fluid carrying waste products and urea removed
    • Clean blood flows through bubble trap to get rid of air bubbles
