Trachea is lined with incomplete rings of

Options

A. Fibrous cartilage
B. Calcified carilage
C. Elastic cartilage
D. Hyaline cartilage

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of the Trachea**: The trachea, also known as the windpipe, is a crucial part of the respiratory system. It serves as a passage for air to travel to and from the lungs.

2. **Role of Cartilage in the Trachea**: The trachea is lined with cartilage to provide structural support. This is essential because the trachea needs to remain open for air to flow freely, even when there is no air inside.

3. **Types of Cartilage**: There are several types of cartilage in the body, including:
- Fibrous cartilage
- Calcified cartilage
- Elastic cartilage
- Hyaline cartilage

4. **Identifying the Correct Type**: The trachea is specifically lined with incomplete rings of hyaline cartilage. This type of cartilage is strong yet flexible, allowing the trachea to maintain its shape while still being able to expand and contract during breathing.

5. **Conclusion**: Therefore, the correct answer to the question "Trachea is lined with incomplete rings of" is **hyaline cartilage**.
