What is the role of passageways in the lung?
If by passageways, you mean the bronchi and bronchioles, they're there as a tunnel to supply oxygen from the outside to the lungs.
Where in the body are epithelial cells found?
Ciliated epithelial cells are found in your pancreas, liver, lung and sinuses.
What is the role of ciliated epithelial in the lung?
The ciliated epithelium in the lung is located on the inside of the bronchioles. The cilia and the moist surface lining captures dirt or toxins that are inhaled. This is coughed up with some of the moist secretions as mucus in order to cleanse the lungs and keep them clear for gas exchange.
What is the smallest conducting passageways of the lungs are called?

What is the smallest brain or heart or lung or stomach?
The Heart
How are ciliated cells and respiratory tract related?
They use mucus created by the root hair cells, to retract the duct between the oviduct and the lung.
What is the cellular abnormality that causes cystic fibrosis?
abnormal chloride channels that trap salt inside cells lining the lung passageways.
What are the smallest subdivisions of the lung visible with the nake eye?

What is the kind of epithelial tissue of pleura?
Pseudostratified ciliated columnar epithelium. This lines the nasal cavity as well as the trachea. The oral cavity, as well as the pharynx, is lined with stratified squamous epithelium, due to obstructions from food.
How smoking damages the respiratory system?
While nicotine has effects on blood flow, these effects are not as significant as the damage to the lung and irritation of the air passages to the lung. One such problem is "smoker's cough", caused by damage to the epithelia of the windpipe. Emphysema caused by the body's immune response to cigarette smoke causes a major loss in lung function and debilitating disease.
What are two consequences of smoking?
Tar build up in the lungs, resulting in ciliated epithelial cells not working correctly, and goblet cells being unable to produce mucas efficiently. Increased risk of lung cancer and 'smokers cough'
