The toxic substance are detoxicated in the human body by

Options

A. Lungs
B. Kidneys
C. Liver
D. Stomach

Answer

**Step-by-Step Solution:**

1. **Identify the Organ Responsible for Detoxification:**
The primary organ in the human body responsible for detoxifying toxic substances is the liver. The liver plays a crucial role in metabolizing drugs and detoxifying harmful substances.

2. **Understand the Role of the Liver:**
The liver processes various substances, including drugs and toxins, converting them into less harmful compounds. This is essential for maintaining the body's overall health and preventing the accumulation of harmful substances.

3. **Identify the Cell Organelle Involved:**
Within the liver cells, the smooth endoplasmic reticulum (SER) is the specific organelle that plays a significant role in detoxification. The SER is involved in the metabolism of lipids and the detoxification of drugs and poisons.

4. **Functions of Other Organs:**
While the liver is the primary organ for detoxification, it's important to note the functions of other organs:
- **Lungs:** Involved in gas exchange, primarily oxygen and carbon dioxide.
- **Kidneys:** Responsible for filtration and excretion of waste products from the blood.
- **Stomach:** Primarily involved in digestion of food.

5. **Conclusion:**
In summary, the detoxification of toxic substances in the human body is primarily carried out by the liver, specifically through the action of the smooth endoplasmic reticulum.
