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 does cilia do in cells?

Mucus in the airways helps trap foreign particles to protect the respiratory system. Cilia are tiny beating hairs that sweep the mucus up to your throat where it is either coughed out or swallowed by the acids in your stomach. The cilia are like a janitor who always sweeps up the messes. If these are destroyed, as can occur with long term smoking, the whole thing comes to a halt and you then have to try to cough and pull up this now thickened mess. it is a nickname for fat people!

How can smoking damage ciliated epithelium cell?

When you smoke your cilia get paralyzed for 90 minutes, that way mucus can not come up. "morning cough" is because your cilia are not paralyzed while you sleep, therefore all that mucus is trying to get coughed up when you wake up. Most people just start up the day with yet more smoking. I really hope this helps. E-mail : aeroally22@aol.com
