how does our lungs clean themselves from small things that get in them like dust?

The cells coating the inside of your lungs (epithelial cells) have little hair-like structures called cilia which can vibrate and move a layer of fluid (mucus) produced by other cells known as goblet cells. Any irritant or pathogen can get stuck in this mucus as it is moved up to a position where it can be coughed out.
Your lungs are lined with tiny hairs which work together in rhythm to push particles to the top of your trachea (where your voice box is), so you can swallow them into your stomach and/or cough them up and swallow them.
