Mucosal surface mechanical cleansing

Mucosal surface mechanical cleansing refers to the combined physical processes—such as mucociliary clearance in the respiratory tract, sloughing and turnover of mucus, and washing by glandular secretions—that remove pathogens, foreign particles, and debris from the body's mucosal surfaces[1][2][5][7]. Mucus, produced by epithelial cells and glands, acts as both a lubricant and a physical barrier; its continual renewal and movement help prevent microbial colonization or invasion[1][2]. Supplemented by chemical antimicrobials (e.g., defensins) and local immune responses, these mechanical processes are essential for protecting respiratory, gastrointestinal, urogenital, and conjunctival surfaces from infection and for maintaining tissue health[1][2][7]. This is a process, not a molecular drug target.
