Which of the following prevents collapsing of Trachea

Options

A. Muscles
B. Diaphragm
C. Ribs
D. Cartilaginous rings

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 that connects the larynx to the bronchi of the lungs. It is a tube-like structure that allows air to pass through.

2. **Identifying the Composition of the Trachea**: The trachea is supported by a series of cartilaginous structures. These structures are not solid but are shaped like incomplete rings.

3. **Function of Cartilaginous Rings**: The cartilaginous rings are C-shaped and are located on the ventral (front) side of the trachea. Their primary function is to provide structural support to the trachea, preventing it from collapsing during breathing.

4. **Conclusion**: Given that the question asks which structure prevents the collapsing of the trachea, the answer is the cartilaginous rings.

**Final Answer**: The cartilaginous rings prevent the collapsing of the trachea.
