Dialysing unit (artificial kidney) contains a fluid which is almost same as plasma except that it has

Options

A. High glucose
B. High urea
C. No urea
D. High uric acid

Answer

To solve the question regarding the composition of the fluid in a dialysing unit (artificial kidney), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Function of the Dialysing Unit**:
- The dialysing unit, commonly referred to as an artificial kidney, is used to filter blood in patients with damaged kidneys. It performs the function of removing waste products from the blood.

2. **Composition of Dialysing Fluid**:
- The fluid in the dialysing unit is designed to mimic the composition of blood plasma. Plasma is the liquid component of blood that carries cells, nutrients, hormones, and waste products.

3. **Identify Key Differences**:
- While the dialysing fluid is similar to plasma, it is crucial to note that it does not contain certain waste products that need to be removed from the blood. The primary waste product that is filtered out during dialysis is urea.

4. **Evaluate the Options**:
- Given the options:
- High glucose
- High urea
- No urea
- High uric acid
- We need to determine which statement accurately reflects the composition of the dialysing fluid.

5. **Select the Correct Answer**:
- Since the dialysing fluid is designed to remove urea from the blood, it should not contain any urea itself. Therefore, the correct answer is "No urea".

### Final Answer:
The fluid in the dialysing unit (artificial kidney) contains a fluid which is almost the same as plasma except that it has **no urea**.
