  • Kidney Failure
    • Dialysis
      • Haemdialysis
        • 1. Toxins from the blood enter the dialysis
        • 2. Toxins pass through the membrane and into the dialysate by diffusion
        • 3. The blood becomes clean and the dirty leaves the dialysis
        • The fluid is the same conc as ions meaning useful ions wont be lost from the blood
        • It is permeable to ions but not large substances
      • Peritoneal dialysis
        • The blood is cleaned through a thin membrane called the peritoneum
        • The peritoneum allows waste products to pass through it and is very rich in small blood vessels
        • Dialysis fluid is passed through the cavity  allowing exchange between the blood and the fluid taking up waste
      • Advantages: fewer diet restrictions, no waiting list
      • need to be carried out everyday, disrupts routine
    • Caused by the inflammation of the glomeri
    • Kidney transplants
      • must come from a healthy person and within the same tissue type
      • The donor kidney can be rejected due to the foreign antigens, the patients body attacks these
      • Advantages: Cheaper, doesn't disrupt everyday life
      • Disadvantages: long waiting list, vulnerable to illness
