The tissue that lines air passages is called epithelium. Specifically, it's pseudostratified ciliated columnar epithelium with goblet cells. Let's break down each part:

* Epithelium: This is a type of tissue that covers the surface of organs and cavities in the body. It's specialized for protection, absorption, secretion, and other functions.

* Pseudostratified: This means the cells appear to be arranged in multiple layers, but they are actually all attached to the basement membrane, making it a single layer.

* Ciliated: This means the cells have hair-like projections called cilia that beat rhythmically to move mucus and debris up and out of the airways.

* Columnar: This describes the shape of the cells, which are tall and narrow like columns.

* Goblet cells: These are specialized cells that produce and secrete mucus, which traps dust, bacteria, and other foreign particles.

This type of epithelium is found in the respiratory tract, from the nasal cavity to the bronchioles. It's crucial for keeping the airways clean and moist, protecting the lungs from infection.
