Abstract: The lung is the principal organ of gas exchange in the body and also carries out a number of non-ventilatory functions including humidification, thermal regulation, mucociliary clearance and elimination of volatile substances. The lung is divided into three main zones, the conducting airways, respiratory bronchioles and alveolar airspaces. The conducting zone begins with the nasal cavity and mouth and then opens through the larynx into the trachea. The trachea divides to form two bronchi that branch like a tree to form smaller passages, the bronchioles. The conducting airways serve as conductors of air from the external environment to the distal gaseous exchange area. The respiratory bronchioles, alveolar ducts and alveoli particulate in gas exchange area and are classified as the terminal respiratory uni and are also called acinus. The adult mammalian lung contains over 40 different cell types, of which at least 8 are found in the epithelial lining of the tracheobronchial airways. These epithelial cells include ciliated cells, basal cells, brush cells, mucous globlet cells, serous cells, Clara cells, type 1, type 2, neuroendocrine cells and a variety of partially differentiated or intermediate cell types.
