bronchial epithelium

The bronchial epithelium is the layer of cells lining the tubes (bronchi) that carry air into your lungs. It acts as a barrier, helping to keep out germs, dust, and harmful substances. These cells also produce mucus, which traps debris and moistens the air you breathe. Tiny hair-like structures called cilia move rhythmically to sweep mucus and trapped particles out of the airways, helping to keep your lungs clean and healthy. The bronchial epithelium plays a vital role in protecting your respiratory system and supporting efficient breathing.
