lung epithelial cells

Lung epithelial cells line the airways and surfaces of the lungs, forming a protective barrier. They help regulate the entry of air, water, and particles, while also producing mucus to trap dust and microbes. These cells are essential for maintaining healthy lung function, enabling gas exchange, and repairing tissue after injury. They also play a role in immune responses, signaling the body to defend against infections. Overall, lung epithelial cells are vital for keeping the lungs clear, protected, and functioning properly.
