What it does : What it does It removes waste from the blood
It removes excess fluid from the blood, and
It keeps electrolytes balanced.
Which are few functions of a normal kidney.
How it works : How it works Dialysis works on the principles of the diffusion and osmosis of solutes and fluid across a semi permeable membrane.
Blood flows by one side of a semi-permeable membrane, and a dialysate or fluid flows by the opposite side
Key terms : Key terms Diffusion: movement of particles from the area of higher concentration to the area on lower concentration
Osmosis: movement of particles from and area of lower concentration to an area of high concentration.
Semi permeable membrane: A semi permeable membrane is a type thin, flexible filter-a barrier that allows only particles smaller than a certain size. Dialyzer (artificial kidney)
Conclusion : Conclusion Hemodialysis performs the basic functions of a kidney, but it can’t replace what a normal kidney can do. It can only do part of what a normal kidney is capable of doing.
