Answer:
Most inspired particles such as dust fail to reach the lungs because of the ciliated mucous membrane of the upper respiratory tract.
Explanation:
Does this help you???
Cilia, which resemble hair-like projections, border the bronchi in the lungs and transport bacteria and detritus up and out of the airways. Goblet cells, which secrete mucus to protect the lining of the bronchus and trap germs, are dispersed throughout the cilia.
What dust fail to reach the lungs?Specialized cells known as macrophages target dust that enters the sacs and lower portions of the airways without cilia. These play a critical role in the lungs' protection. The air sacs are kept clean by them. Virtually swallowing the particles are macrophages.
Most of the dust particles are captured by the mucus they create. The mucus is moved upward and out into the throat by tiny hairs called cilia that coat the walls of the air tubes. There, it is either swallowed whole or coughed up and vomited out.
Therefore, Most inspired particles such as dust fail to reach the lungs because of the ciliated mucous membrane of the upper respiratory tract.
