WebAug 4, 2024 · Apart from comprising the epithelial lining of various organs, production of large glycoproteins and carbohydrates, the most important function of goblet cells is the secretion of mucus. The mucus is a gel like substance that is composed mainly of mucins, glycoproteins and carbohydrates. Webgoblet cells can represent a much greater potential for secretion than do the submucosal glands. Thus, it can be argued that the goblet cell represents the principal front-line defender of the airway.
