Biology B3 3.3 Dialysis - an artificial kidney.

HideShow resource information
What treatment can patients receive when kidneys fail to keep them alive?
Dialysis.
1 of 11
What is the the function of a dialysis machine?
A dialysis machine does the work of the kidneys and keeps patients alive.
2 of 11
In what circumstance would a dialysis machine no longer be necessary for a patient with kidney failure?
If a successful kidney transplant is carried out.
3 of 11
Why does the dialysis fluid contain glucose and mineral ions?
If the dialysis fluid was water only, all the useful solutes would diffuse out of the blood as well as the urea.
4 of 11
What job does a dialysis machine do?
A dialysis machine carries out the same job as the kidneys.
5 of 11
How does the blood flow during dialysis?
The blood flows between partially permeable membranes.
6 of 11
What concentration of useful substances (e.g. glucose and mineral ions) does the dialysis fluid contain?
The same concentration as the patient's blood does, this means that these substances do not diffuse out of the blood so they do not need to be reabsorbed.
7 of 11
What diffuses out from the patient's blood during dialysis?
Urea.
8 of 11
What does dialysis restore?
The concentration of substances in the blood back to normal, but needs to be carried out at regular intervals.
9 of 11
What happens if a kidney becomes available?
The patient may have a kidney transplant and if the transplant is successful they may not need further dialysis.
