Options

A. Glottis
B. Gullet
C. Oesophagus
D. None of the above

Answer

**Step-by-Step Solution:**

1. **Understanding the Role of the Epiglottis:**
The epiglottis is a flap made of cartilage located at the base of the tongue. Its primary function is to prevent food from entering the trachea during swallowing.

2. **Pathway of Food:**
When food is swallowed, it moves from the buccal cavity (mouth) to the pharynx. The pharynx is a shared passageway for both food and air.

3. **Branches of the Pharynx:**
The pharynx opens into two main pathways:
- The trachea (windpipe) which is the anterior passage.
- The esophagus (food pipe) which is the posterior passage.

4. **Function of the Epiglottis During Swallowing:**
When food enters the pharynx, the epiglottis acts as a flap that closes over the trachea. This prevents food from entering the trachea and directs it into the esophagus.

5. **Conclusion:**
Therefore, the epiglottis prevents the entry of food into the trachea (also referred to as the glottis in this context).

**Final Answer:**
The epiglottis prevents the entry of food into the **trachea (glottis)**.
