Also referred to as the mucociliary escalator; covers bronchi, bronchioles, and nose in the respiratory tract. It is composed of the mucus-secreting goblet cells and ciliated epithelium found in the mucosa lining of the respiratory tract. The cilia are continually beating, pushing mucus up and out into the throat, forming a major barrier against infection. Microorganisms trying to infect the respiratory tract are caught in the sticky mucus and moved up by this mucuciliary escalator. The mucus is pushed into the throat and swallowed, then digested by the body, preventing the microorganisms from causing any harm/infection to the body
