a) The periodical filtering of blood through artificial kidney is termed as ‘Dialysis’.
A kidney can filter 100-150 quarts of blood every day. If the kidneys are not functioning properly, waste starts accumulating in the blood. This results in coma and even death.
To cure this, the patient is subjected to dialysis. Dialysis maintains the body balance in the following ways:
- It controls blood pressure.
- It removes excess water and metabolic wastes from the body.
- Prevents chemicals such as potassium, bicarbonate and sodium from reaching hazardous levels.
b) It performs the function of kidneys if they have failed.
