What are the short hair like structures found in the lungs?

The short hair-like structures found in the lungs are called cilia. These microscopic projections line the respiratory tract and play a crucial role in clearing mucus and debris from the airways. By beating in a coordinated manner, cilia help move trapped particles and pathogens upward towards the throat, where they can be swallowed or expelled. This function is essential for maintaining respiratory health and preventing infections.
