Apart from liver urea formation also takes plce in

Options

A. Kidney
B. Spleen
C. Brain
D. Adrenal cortex

Answer

### Step-by-Step Solution:

1. **Understanding Urea Formation**: Urea is a waste product formed from the breakdown of proteins in the body. The primary site for urea formation is the liver, where ammonia is converted into urea through the urea cycle.

2. **Identifying Other Sites of Urea Formation**: The question asks for places other than the liver where urea formation occurs.

3. **Evaluating the Options**:
- **Kidney**: The kidneys are primarily responsible for the excretion of urea through urine. They do not significantly contribute to the formation of urea.
- **Spleen**: The spleen is involved in the recycling of red blood cells and does not participate in urea formation.
- **Brain**: The brain does produce small amounts of urea and ammonia as a byproduct of protein metabolism. However, this is not a significant site of urea formation compared to the liver.
- **Adrenal Cortex**: The adrenal cortex is involved in hormone production and does not contribute to urea formation.

4. **Conclusion**: Among the options, the brain is the only site that produces urea, albeit in small amounts. Therefore, the correct answer is the brain.

### Final Answer:
Apart from the liver, urea formation also takes place in the **brain**.
