To assist in removing dust particles and other unwanted foreign bodies that have entered the air passages.
The lungs tissues are made up mainly of squamous epithelial tissue (called alveolar epithelium in the lungs). This type of tissue serves a critical function within the lungs because it allows the transfer and exchange of gases with little or no resistance. The advantages are a short distance between the Oxygen in the alveoli and the blood in the capillaries.The lungs also contain ciliated epithelium. A function of ciliated epithelium is stimulation of goblet cells to produce a mucous-like substance that not only lubricates but also traps pathogens and particles in the bronchi.
Simple squamous epithelium is also known as pavement epithelium due to its thin, flattened shape resembling a pavement. It is found in areas where filtration or diffusion is the primary function, such as in the alveoli of the lungs and the lining of blood vessels.

This type of epithelium is frequently found in glands, and the pancreas, where its function is secretion.
The function of pseudostratified columnar epithelium in the human body is to protect and line the respiratory tract, including the nasal cavity, trachea, and bronchi. It helps to trap and move mucus and particles, as well as facilitate the movement of air in and out of the lungs.
The structure in the lungs that contains the thinnest epithelium is the alveoli. Alveoli are air sacs where the exchange of gases takes place.
The ciliated epithelium of the tracheobronchial tree helps to remove mucus and foreign particles from the respiratory tract by moving them upwards towards the throat to be either swallowed or expelled. This movement of the cilia helps to protect the lungs from infections and irritants.

The dominant function of stratified epithelium is to protect underlying structures from mechanical wear and tear.

With each breath, the lungs take in oxygen and remove carbon dioxide. the lungs have a great surface area thanks to the alveoli; have an extremely thin (1 cell thick) epithelium.
thin wall - rapid diffusion small gaps - allow diffusion and actv tspt goblet cells in lung epithelium - secrete mucus to trap bacteria ciliated epithelium - waft mucus out of the lungs squamous - stretch and recoil around a blood vessel there are about another 10 types of specialised epithelium tissues and cells in the human body
