Mucus is primarily produced by goblet cells located in the epithelial tissues lining various organs, including the respiratory and gastrointestinal tracts. It serves several essential functions, such as lubricating and protecting these surfaces, trapping pathogens and particulates, and facilitating the movement of materials through the digestive system. In the respiratory system, mucus helps to trap dust and microbes, preventing them from entering the lungs.
