In humans, the respiratory tract is the part of the anatomy of the respiratory system involved with the process of respiration. The respiratory tract is lined with respiratory mucosa or respiratory epithelium.[1] Air is breathed in through the nose or the mouth. In the nasal cavity, a layer of nasal mucosa acts as a filter and traps pollutants and other harmful substances found in the air. Next, air moves into the pharynx, a passage that contains the intersection between the oesophagus and the larynx. The opening of the larynx has a special flap of cartilage, the epiglottis, that opens to allow air to pass through but closes to prevent food from moving into the airway
