Answer

### Step-by-Step Solution:

1. **Identify the Location of Vocal Cords**:
- Vocal cords are located in the larynx, which is also known as the voice box.

2. **Understand the Structure of Vocal Cords**:
- The vocal cords consist of muscle and cartilage. They have a membranous flap that can open and close.

3. **Explain the Function of Vocal Cords**:
- When air is exhaled from the lungs, it passes through the vocal cords. The membranous flaps of the vocal cords come together and vibrate, producing sound.

4. **Describe the Process of Sound Production**:
- During exhalation, as air moves out, the vocal cords vibrate due to the air pressure, creating sound. This process is essential for voice production.

5. **Mention Related Structures**:
- The pharynx serves as a common pathway for food and air. The glottis is the opening of the windpipe (trachea), which leads to the lungs. The trachea is supported by C-shaped cartilage and divides into the bronchial tubes before entering the lungs.

### Final Answer:
Vocal cords occur in the larynx.
