Question

Explain dialysis with the help of a diagram.

Answer 1

If one or both of a patient's kidneys fail (or fail to operate to a sufficient level) then dialysis may be used to regulate the concentration of urea and solutes in the blood. Although this process may be clinically effective it is often inconvenient for the patient so may be used as only a short-term measure - until kidney transplant becomes possible.

The following diagram is a much simplified representation of kidney dialysis. (There are many different ways of illustrating this - we have seen other diagrams laid out in completely different ways yet summarising the same processes.)



As shown in the diagram above, there are two separate circuits along which liquids flow. 
They are:

The blood-flow from the patient, into the dialyser, through the dialyser, then back to the patient, andThe flow of dialysate around its own circuit which includes the dialyser plus some other stages.

Answer 2

Dialysis:-

It is the treatment in which waste from the blood is removed by taking blood out the body  and then sending it back to body after purification.

Explanation:

1. In the process of dialysis, the blood from the body is taken out via artery.
2. This blood is pumped to the dialyser and before this an anticoagulant is added to blood to prevent its clotting.
3. After purification in dialyzer, the blood is sent to body again vai vein.

This dialyser is called artificial kidney and haemodialyzer.
