- Epithelial surfaces provide the first line of defense against infection by the use of several types of mechanisms. One of the chemical mechanisms used by epithelia is: Joining of epithelial cells by tight junctions Secretion of antimicrobial peptides by epithelial cells Production of mucus, tears, or saliva in the nose, eyes, and oral cavity Movement of mucus by cilia Peristalsis in the gastrointestinal tractThe steps of how to make a wet mouth of cheek epithelial cells.place the steps of how to prepare a wet mouth in the correct order form left to right?46.
