Which of the following structures plays an important role in the elimination of diolesterol and degraded steroid hormones?

Options

A. Lungs
B. Liver
C. Sweat gland
D. Sebaceous gland

Answer

To determine which structure plays an important role in the elimination of diolesterol and degraded steroid hormones, we can follow these steps:

### Step 1: Understand the substances involved
- **Diolesterol** and **degraded steroid hormones** are substances that can be toxic to the body if they accumulate.

### Step 2: Identify the role of the liver
- The liver is known for its detoxification processes. It metabolizes and eliminates various toxins, including drugs, alcohol, and harmful metabolites. This includes the breakdown and elimination of steroid hormones and cholesterol derivatives.

### Step 3: Evaluate the options
1. **Lungs**: Primarily involved in gas exchange, specifically the elimination of carbon dioxide. They do not play a significant role in detoxifying diolesterol or steroid hormones.
2. **Liver**: As discussed, it detoxifies and eliminates toxins, including diolesterol and degraded steroid hormones.
3. **Sweat glands**: They excrete sweat, which contains water, salts, and some waste products, but they do not play a major role in eliminating diolesterol or steroid hormones.
4. **Sebaceous glands**: These glands secrete sebum, which contains lipids and provides a protective layer for the skin, but they are not involved in the detoxification of diolesterol or steroid hormones.

### Step 4: Conclusion
- Based on the evaluation, the structure that plays an important role in the elimination of diolesterol and degraded steroid hormones is the **liver**.

### Final Answer:
The correct answer is **liver**.
