bronchial epithelial cells

Bronchial epithelial cells are specialized cells that line the airways of the lungs, known as the bronchi. They play a crucial role in protecting the lungs from inhaled pathogens, pollutants, and irritants. These cells produce mucus, which traps particles, and contain tiny hair-like structures called cilia that help move mucus out of the airways. This process keeps the airways clear and helps maintain healthy lung function. In various respiratory conditions, such as asthma or infections, the behavior of bronchial epithelial cells can change, contributing to inflammation and increased mucus production.
