Find the incorrect match.

Options

A. Pharynx- common passage for food and air
B. Larynx-helps in sound production
C. Epiglottis-part of trachea
D. Trachea- a tube like structure extending upto the mid thoracic cavity

Answer

To solve the question "Find the incorrect match," we will analyze each of the given options related to the respiratory system.

### Step-by-Step Solution:

1. **Identify the Options**: The options provided are:
- Pharynx
- Larynx
- Epiglottis
- Trachea

2. **Analyze the Pharynx**:
- The pharynx is indeed a common passage for both food and air.
- It is divided into three parts: nasopharynx, oropharynx, and laryngopharynx.
- This statement is correct.

3. **Analyze the Larynx**:
- The larynx is known as the sound box and is responsible for voice production.
- It is made of cartilage and plays a crucial role in phonation.
- This statement is also correct.

4. **Analyze the Epiglottis**:
- The epiglottis is a flap-like structure that covers the trachea during swallowing to prevent food from entering the airway.
- The statement claims that the epiglottis is a part of the trachea, which is incorrect. The epiglottis is not a part of the trachea; rather, it is a protective covering.
- This statement is incorrect.

5. **Analyze the Trachea**:
- The trachea is a tube-like structure that extends from the larynx down to the mid-thoracic cavity, where it bifurcates into the right and left bronchi.
- This statement is correct.

6. **Conclusion**:
- The only incorrect match among the options is the statement regarding the epiglottis, which incorrectly identifies it as a part of the trachea.

### Final Answer:
The incorrect match is **Epiglottis** (it is a covering of the trachea, not a part of it).
