If liver is removed, which component of blood will increase ?

Options

A. Urea
B. Protein
C. Uric acid
D. Ammonia

Answer

To solve the question "If liver is removed, which component of blood will increase?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Function of the Liver**:
- The liver plays a crucial role in detoxification and metabolism, particularly in the conversion of ammonia (a toxic byproduct of protein metabolism) into urea, which is less toxic and can be excreted safely by the kidneys.

2. **Identify the Process of Urea Formation**:
- Proteins are broken down into amino acids. During this process, ammonia is produced. The liver then converts this ammonia into urea through the urea cycle. This is an essential function of the liver.

3. **Consider the Consequences of Liver Removal**:
- If the liver is removed, the body will no longer be able to convert ammonia into urea. As a result, ammonia will accumulate in the bloodstream because it cannot be processed.

4. **Determine Which Component Increases**:
- Since the liver is responsible for converting ammonia into urea, the removal of the liver will lead to an increase in the concentration of ammonia in the blood. However, since urea is the end product of this process, the concentration of urea will also increase due to the inability to excrete it properly.

5. **Conclude the Answer**:
- The primary component that will increase in the blood due to the removal of the liver is **urea**. This is because, without the liver, the conversion of ammonia to urea cannot occur, leading to a buildup of urea in the bloodstream.

### Final Answer:
If the liver is removed, the component of blood that will increase is **urea**.
