The main function of the trachea, commonly known as the windpipe, is to provide a clear and open airway for the passage of air to and from the lungs. It acts as a conduit for air during respiration, allowing oxygen to enter the lungs for gas exchange and facilitating the removal of carbon dioxide. The trachea is lined with ciliated mucous membranes that help trap and expel foreign particles and pathogens, contributing to the respiratory system's protective functions. Additionally, the trachea helps to humidify and warm the air before it reaches the lungs.
