In kidney failure condition urea can be removed by ____process.

Answer

**Step-by-Step Solution:**

1. **Understanding Kidney Function**: The kidneys are essential organs responsible for filtering waste products, including urea, from the blood. In a healthy state, they efficiently remove these wastes through urine.

2. **Identifying Kidney Failure**: In kidney failure, the kidneys lose their ability to filter blood effectively. This leads to the accumulation of urea and other waste products in the body, which can be toxic.

3. **Need for Urea Removal**: Since the kidneys are not functioning properly, there is a critical need to remove urea from the bloodstream to prevent harmful effects on the body.

4. **Dialysis as a Solution**: The process used to remove urea in cases of kidney failure is called dialysis. Dialysis is a medical procedure that mimics the kidney's filtering function.

5. **How Dialysis Works**: During dialysis, blood is drawn from the body and passed through a machine known as a hemodialyzer (or artificial kidney). This machine filters out urea and other waste products.

6. **Return of Filtered Blood**: After the blood is filtered, it is returned to the body, ensuring that the harmful substances are removed while maintaining the necessary components of the blood.

7. **Conclusion**: Therefore, in kidney failure conditions, urea can be removed by the process of dialysis.

**Final Answer**: In kidney failure condition, urea can be removed by **dialysis**.
