To line the airways and make mucus, which lubricates and protects the lung
There are numerous different cell types in the lungs. Epithelial cells make up the majority of lung cells. Mucus is produced by epithelial cells that line the airways and coat and shield the lung. Additionally, the lung cells contain blood, nerve, hormone-producing, and structural or supporting cells.
Air enters your lungs when you inhale (breath), and the oxygen in that air travels to your blood. A waste gas called carbon dioxide travels from your blood to your lungs at the same time and is exhaled (breathed out). Gas exchange is a procedure that is vital to life.
the bronchiolar epithelial cells, also known as airway cells, which are bordered with smooth muscle, and the alveolar epithelial cells, which make up the tiny sacs where gas exchange occurs
