What type of cells is responsible for secreting mucus in the airways?

Goblet cells are specialized epithelial cells found in the respiratory tract and other mucous membranes. Their primary function is to secrete mucus, which plays a crucial role in protecting and lubricating the airways. Mucus traps inhaled particles, pathogens, and other debris, helping to clear them from the airways and prevent infections.

Epithelial cells form the overall lining of the airways but do not specifically secrete mucus; they serve as a barrier and play various other roles, including transport and protection. Ciliated cells have hair-like structures, or cilia, that help move mucus out of the airways but do not produce the mucus themselves. Basal cells serve as progenitor cells for renewing the airway epithelium but do not participate directly in mucus secretion. Thus, the unique function of goblet cells in mucus production is what makes this answer correct.
