Dialysis is an artificial process used to remove water and waste substances from the blood when the kidneys fail to function properly.
Dialysis works on the principles of the diffusion of solutes and ultrafiltration of fluid across a semipermeable membrane.
Why Is Dialysis (Haemodialysis) Necessary?
The total amount of Urine Produced is regulated by:
The total amount of Nitrogenous waste Produced.
Fecal matter is not produced by metabolism, removal of feces cannot be considered as excretion.
