explain homeo dialysis for Artificial kidney
Answers
Answer:
If one kidney is damaged or removed, then the other kidney alone can fulfil excretory needs.
However, the failure of both the kidneys allows urea and other wastes to accumulate in the blood.
Such a patient undergoes dialysis.
In dialysis, an artificial kidney is used.
Mechanism of Dialysis:
The artificial kidney contains tubes made of cellophane with a semi-permeable lining.
These tubes are suspended in a tank filled with a dialysing solution.
This fluid contains water and glucose in concentrations similar to those in blood.
The patient’s blood is led from the radial artery and cooled at 0°C.
Then anticoagulant heparin is added to the blood.
Blood is then passed through semi-permeable coiled cellophane tubes.
The tubes allow small molecules such as urea, creatinine, uric acid to pass out.
Also metabolic wastes are filtered out in the surrounding solution.
But the macromolecules such as proteins are retained in the blood.
Purified blood is then mixed with antiheparin and warmed to the body temperature.
The purified blood is returned through a vein in the same arm.
The function of dialysis is similar to the function of the kidney, but the only difference is there is no reabsorption during dialysis.

dialysis is a a disease which is infection in kidney
