Which of these is anatomically incorrect?

Options

A. The nose has two nasal cavities.
B. The pharynx connects the nasal and oral cavities to the larynx.
C. The larynx contains the vocal cords.
D. The trachea enters the lungs

Answer

To determine which statement is anatomically incorrect, we will analyze each option provided in the question step by step.

### Step-by-Step Solution:

1. **Understanding Anatomy**:
- Anatomy refers to the internal structure of organisms. To solve the question, we need to identify which statement about the anatomical structures is incorrect.

2. **Analyzing Option 1**:
- The statement is that "the nose has two nasal cavities."
- This is correct because the human nose does indeed have two nasal cavities (the left and right nasal passages).

3. **Analyzing Option 2**:
- The statement is that "the pharynx connects the nasal and oral cavities to the larynx."
- This is also correct. The pharynx serves as a passageway for both air and food, connecting the nasal cavity and oral cavity to the larynx.

4. **Analyzing Option 3**:
- The statement is that "the larynx contains the vocal cords."
- This is correct as well. The larynx is known as the voice box and contains the vocal cords, which are essential for sound production.

5. **Analyzing Option 4**:
- The statement is that "the trachea enters the lungs."
- This statement is incorrect. The trachea, or windpipe, does not directly enter the lungs; rather, it branches into the bronchi, which then enter the lungs.

6. **Conclusion**:
- After analyzing all options, we find that option 4 is anatomically incorrect. Therefore, the answer is option 4.

### Final Answer:
**Option 4: The trachea enters the lungs.** (This statement is anatomically incorrect.)
