Which of the following is a part of both digestive tract as well as respiratory tract?

Options

A. Trachea
B. Larynx
C. Nose
D. Pharynx

Answer

To solve the question of which structure is part of both the digestive tract and the respiratory tract, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: We need to identify a structure that serves a dual purpose in both the digestive and respiratory systems.

2. **Analyzing the Options**:
- **Option A: Tract** - This is too vague and does not specify a structure.
- **Option B: Larynx** - The larynx is primarily part of the respiratory system, as it is involved in sound production and protecting the trachea against food aspiration.
- **Option C: Nose** - The nose is primarily part of the respiratory system, responsible for filtering, warming, and humidifying air.
- **Option D: Pharynx** - The pharynx connects the mouth to both the esophagus (part of the digestive tract) and the larynx (part of the respiratory tract).

3. **Identifying the Correct Answer**: The pharynx is the only structure that connects both the digestive system (esophagus) and the respiratory system (larynx). Therefore, the correct answer is **Option D: Pharynx**.

### Final Answer:
The part of both the digestive tract as well as the respiratory tract is **Pharynx** (Option D).
