Answer

To solve the question, "Sound is produced by humans when air passes through the narrow slit between the ________ present in the larynx," we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Location of Sound Production**:
- Sound in humans is produced in the larynx, which is an organ located in the throat.

2. **Understand the Mechanism of Sound Production**:
- Within the larynx, there are structures that are crucial for sound production. These structures vibrate when air passes through them.

3. **Identify the Structures Involved**:
- The specific structures responsible for producing sound are known as vocal cords (or vocal folds). They are thin membranes that can open and close to create sound.

4. **Explain the Process**:
- When air is pushed from the lungs through the narrow slit between the vocal cords, it causes them to vibrate. These vibrations produce sound waves, which we perceive as sound.

5. **Fill in the Blank**:
- Based on the above understanding, we can fill in the blank in the question. The correct answer is "vocal cords."

### Final Answer:
Sound is produced by humans when air passes through the narrow slit between the **vocal cords** present in the larynx.
