Ammonia is converted into urea in _____ and filtered from blood and excreted out by_____

Answer

**Step-by-Step Solution:**

1. **Understanding Ammonia Production**: Ammonia is produced as a byproduct of protein metabolism in the body. It is highly toxic and cannot be excreted directly in humans due to its toxicity and the large amount of water required for its excretion.

2. **Conversion of Ammonia to Urea**: To safely eliminate ammonia, it is converted into urea through a process known as the urea cycle. This conversion primarily occurs in the liver. The liver contains specific enzymes that facilitate this transformation.

3. **Role of the Liver**: The liver is the organ responsible for the conversion of ammonia into urea. This process is crucial because urea is much less toxic and can be excreted with less water.

4. **Excretion of Urea**: Once urea is formed in the liver, it is transported through the bloodstream to the kidneys. The kidneys filter the blood, removing waste products, including urea.

5. **Function of the Kidneys**: The kidneys are the organs responsible for filtering urea from the blood and excreting it from the body. They perform this function through a series of processes, including filtration, reabsorption, and secretion.

6. **Final Answer**: Therefore, the complete answer to the question is: Ammonia is converted into urea in the **liver** and filtered from the blood and excreted out by the **kidneys**.
