How air is cleaned in the nasal chambers?

Explanation

### Step-by-Step Solution:

1. **Introduction to Nasal Chambers**: The nasal chambers are the initial part of the respiratory system where air enters the body. They play a crucial role in conditioning the air before it reaches the lungs.

2. **Ciliated Epithelium**: The nasal chambers contain a type of tissue called ciliated epithelium. This tissue has tiny hair-like structures (cilia) that move in a coordinated manner. The primary function of the cilia is to act as a filter, trapping dust and other particulate matter from the air.

3. **Goblet Cells and Mucus Production**: Within the ciliated epithelium, there are specialized cells known as goblet cells. These cells secrete mucus, which is a sticky substance that helps trap dust particles, allergens, and other impurities present in the inhaled air.
