Tracheal wall has …...... Cartilage

Options

A. Option1 Hyaline
B. Option2 Fibrous
C. Option3 Elastic
D. Option4 Calcified

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of the Trachea:**
- The trachea, commonly known as the windpipe, is a crucial part of the respiratory system. It connects the larynx to the bronchi, allowing air to flow to and from the lungs.

2. **Identifying the Composition of the Tracheal Wall:**
- The wall of the trachea is reinforced by a series of cartilaginous rings. These rings are essential for maintaining the structure of the trachea and preventing it from collapsing during breathing.

3. **Types of Cartilage:**
- There are several types of cartilage in the body: hyaline, fibrous, elastic, and calcified cartilage. Each type has distinct properties and functions.

4. **Determining the Type of Cartilage in the Trachea:**
- The tracheal wall is specifically supported by C-shaped rings made of hyaline cartilage. This type of cartilage is known for its smooth and glassy appearance and provides both support and flexibility.

5. **Function of Hyaline Cartilage in the Trachea:**
- Hyaline cartilage in the tracheal wall helps maintain the shape of the trachea, preventing it from collapsing while allowing for the expansion and contraction necessary during breathing. It also contains type 2 collagen, which contributes to its elasticity.

6. **Conclusion:**
- Based on the information gathered, the correct answer to the question "Tracheal wall has …...... Cartilage" is **hyaline cartilage**.

**Final Answer:**
The tracheal wall has **hyaline cartilage**.
