The bronchus in the lungs are lined with hair-like projections called cilia that move microbes and debris up and out of the airways. Scattered throughout the cilia are goblet cells that secrete mucus which helps protect the lining of the bronchus and trap microorganisms.
The purpose of mucus is to lubricate and protect the organs that it lines. Mucus is supposed to be thin, clear, and watery. Cloudy, yellow, or green mucus are signs of an infection.

What occurs when the cilia that line your trachea and bronchi?

What is the purpose of the mucous membrane and cilia in the trachea?
Mucous membranes and cilia in the trachea trap and eliminate particulate matter from inhaled air. The membranes also warm and moisten incoming air.
Where are the cilia in the respiratory system located?
In the lining of the trachea, bronchi, and bronchioles.
What is the tube held open by rings of cartilage lined with cilia and mucous membrane?
The trachea.
Which organelle is responsible for removing foreign material from the trachea and bronchi?
Cilia are responsible for removing foreign material from the trachea and bronchi. They are like little dusters that remove germs and bacteria.
Why are the cilia and mucus in the nasal cavity and trachea important?
The combination of cilia and mucous helps to filter out solid particles from the air.
Where are cilia located?
Cilia are found on the outside of the cell as projections for bacteria and virus.
What is a 12 cm air tube containing mucous membranes and cilia to trap dust and pollen and bacteria?
trachea
Why are cilia in the trachea important?
These are tiny "fingers" which move mucous. The mucous is sticky and traps dust, pollen and other particles. Together the cilia move the mucous out of the lungs. If this didn't happen these things trapped in the mucous would cause damage to the lungs and a person would have breathing difficulties over time.
What sticks to the cilia?
Mucous, made by mucous glands, stick to the cilia of cells that are found in the mucous membranes.
Are the cells that line the bronchi covered with cilia to help move mucous or mucus out of the lungs?
They move 'mucus' and are cells that make up a 'mucous' membrane. Mucus is a noun, the thing that is secreted, and mucous is an adjective describing the quality of the thing that makes the mucus.
What does cigarette smoking do to the cilia?
When we breathe in air through our nose and mouth, the air passes down the windpipe (trachea) and bronchial tubes into the lungs. The cilia which are made up of small hairs and mucous (a sticky fluid also found in the nose) help to clean this air as it moves down and into the lungs by removing small pieces of dirt, dust, and germs. Cigarette smoke will damage the cilia since it will be harder to get rid of the bacteria and dust particles inside the windpipe (trachea) and the bronchi. This will be dangerous since it will enter to the lungs and cause/ develop lung infections.
