How Kidney Filters
The kidney FILTERS the blood by having a filter between the bowmans capsule and blood vesels. This filters and lets little molecules such as water ions and urea through the filter however big molecules like Protein can't fit through. However when travelling down the nephron important ions such as glucose are reabsorbed back into the blood.
Flows through Semi Permeable Membrane
Fluid in Dialysis contains same concentration of ions and useful substances as patients blood has
Bad substances get filtered out such as urea
Dialysis restores the normal concentration back to blood
However has to be repeated all the while.
Must Match tissue
However can be rejected by immune system like foreign body
