Answer

To answer the question "The toxic substances are detoxified in the human body by," we will analyze the options provided and identify the correct answer step by step.

### Step 1: Understand the Concept of Detoxification
Detoxification is the physiological process of removing toxic substances from the body. This process is essential for maintaining health and preventing damage caused by harmful compounds.

### Step 2: Evaluate the Options
The options given are:
1. Lungs
2. Kidney
3. Liver
4. Stomach

### Step 3: Analyze Each Option
- **Lungs**: The primary function of the lungs is gas exchange (oxygen and carbon dioxide). While they can expel some volatile substances, they are not primarily responsible for detoxifying the body.

- **Kidney**: The kidneys filter blood and remove waste products through urine. They play a role in excreting some toxins but are not the main organ for detoxification.

- **Liver**: The liver is the central organ for detoxification. It contains specialized cells called hepatocytes that metabolize and detoxify harmful substances, including drugs and toxins. The liver converts these substances into less harmful compounds that can be excreted from the body.

- **Stomach**: The stomach primarily functions in digestion. It does not play a significant role in detoxifying substances.

### Step 4: Identify the Correct Answer
Based on the analysis, the liver is the organ responsible for detoxifying toxic substances in the human body. Therefore, the correct answer is:

**The liver (Option 3)**.

### Conclusion
The toxic substances are detoxified in the human body by the liver, which contains hepatocytes that metabolize and inactivate harmful compounds.
