themodialysis is the process of the state of being removal of the urea and the nitrogenous wastes from blood by a man made artificial procedure .
- blood is drained out slowly and passed through dialyzer .
- heparin mixed
- dialyzer contains network of cellophane tubes inside an isotonic medium devoid of nitrogenous wastes
- dialyzer sucks out the wastes based on simple diffusion .
- down the concentration gradient
- purified blood is pumped back to a suitable vein .
- anti-heparin mixed .
we know that , the kidney removes the harmful wastes ( metabolic wastes ) .
then the hemodialysis helps to the patients by purifying the blood for who are suffering from kidney infections , whose kidneys are dead .
