Artificial kidney (Dialysing unit ) is a machine that is used for filtration of blood in the people whose kidneys are failed or damaged by the process called Dialysis.
Dialysis fluid is produced by the blending of treated water with electrolytes at the patient's bedside. The composition of the dialysis fluid should match that of plasma except for the nitrogenous waste (urea).
So the answer is 'No urea'.

The dialysing unit (fluid) has the same composition as that of plasma except the nitrogenous waste (urea). Other options are wrong, as dialysing unit will not have high glucose, high urea or high uric acid.

Dialysing unit (artificial kidney) contains a fluid which is almost the same as plasma except that it has no urea.
Explanation:
The dialysing unit, also known as an artificial kidney, is a medical device used in the process of dialysis. Dialysis is a treatment used for individuals with kidney failure to help remove waste products and excess fluid from their blood.
Role of the Dialysing Unit:
The dialysing unit consists of a semi-permeable membrane that allows the passage of certain substances while preventing others from passing through. It is designed to mimic the functions of a natural kidney by filtering the blood and removing waste products that accumulate in the body.
Comparison with Plasma:
Plasma is the liquid component of blood and contains various substances such as water, electrolytes, proteins, and waste products like urea. The fluid used in the dialysing unit is created to closely resemble plasma, but with one crucial difference - it does not contain urea.
Reason for No Urea:
Urea is a waste product that is produced in the liver and excreted by the kidneys. In individuals with kidney failure, the kidneys are unable to effectively remove urea from the bloodstream. Therefore, the dialysing unit is designed to eliminate urea from the blood during the dialysis process.
Importance of Urea Removal:
Urea is a toxic substance that can lead to various complications if it accumulates in the blood. By removing urea, the dialysing unit helps maintain the balance of electrolytes and other substances in the body, preventing the harmful effects of uremia.
Other Waste Product Removal:
While urea is the primary waste product removed during dialysis, the dialysing unit also helps eliminate other waste products such as creatinine and excess electrolytes. This ensures that the blood is cleared of harmful substances and restored to a more balanced state.
Conclusion:
The dialysing unit used in the process of dialysis contains a fluid that closely resembles plasma, but with no urea. This is essential for effectively removing the toxic waste product urea from the blood, helping maintain the overall health and well-being of individuals with kidney failure.
