working model of human dialysis in science
Answers
Explanation:
Dialysis is a procedure that is a substitute for many of the normal duties of the kidneys like filtering of wastes in case of kidney failure.
Healthy kidneys remove excess of fluid, wastes, and minerals from the body.
If the kidneys fail to function, wastes may accumulate in the body, the body may retain excess fluid, and blood pressure may rise. This can even lead to death.
In such a case, an artificial kidney or hemodialysis is useful.
In hemodialysis, only a few drops of blood are allowed to flow, through a special filter that removes wastes and extra fluid.
The detoxified blood is then returned to the body.
The special filter used in dialysis consists of a number of tubes with semi-permeable lining, suspended in a tank filled with the dialysis fluid.
