Question

5. Why is dialysis an example of diffusion?​

Answer 1

Answer:

In dialysis the higher concentrations of urea and uric acid moves from inside blood to the solution which has less concentration of these materials which was is a diffusion

Explanation:

A process in which a material moves from the region of higher concentration to the region of lower concentrations

⇝DIALYSIS

Dialysis is the medical term for removing the waste and extra fluid from your blood that your kidneys can no longer remove themselves. When the waste is gone, you may feel better.

⇝PRINCIPLES

Dialysis removes the waste products and extra fluid from your blood by filtering them through a membrane/filter, similar to the way healthy kidneys would. During dialysis, blood is on one side of the membrane/filter and a special fluid called dialysate (containing water, electrolytes, and minerals) is on the other. Small waste products in your blood flow through the membrane/filter and into the dialysate.

Larger particles, like red blood cells, remain in your blood. In this way, your blood is cleaned.

⇝DIALYSIS, A DIFFUSION?

As the dialysis fluid has no urea in it, there is a large concentration gradient - meaning that urea moves across the partially permeable membrane, from the blood to the dialysis fluid, by diffusion. This is very important as it is essential that urea is removed from the patients' blood.
