respiratory epithelium

Respiratory epithelium is a specialized lining that covers most of the respiratory tract, including the nose, throat, and airways. It consists mostly of ciliated cells, which have tiny hair-like structures called cilia that move rhythmically to clear mucus and trapped debris out of the airways, helping to keep the lungs clean. The epithelium also contains mucus-producing cells that trap dust, bacteria, and other particles. This layer is essential for protecting your respiratory system and maintaining healthy breathing. Its structure adapts along different parts of the respiratory tract for optimal function.
