What lines the conducting airways?

The conducting airways are lined primarily with respiratory epithelium, which is a type of pseudostratified ciliated columnar epithelium. This epithelium contains goblet cells that secrete mucus to trap particles and pathogens. Additionally, the airways are supported by cartilage and smooth muscle, which help maintain their structure and regulate airflow. The cilia on the epithelial cells help move mucus and trapped debris out of the airways, contributing to respiratory health.
