Which epithelial cells manufacture and store lubricating mucus?

Goblet cells are specialized epithelial cells primarily responsible for the production and secretion of mucus. They are found in various tissues, particularly in the respiratory and gastrointestinal tracts, where their mucous secretion plays a crucial role in lubrication and protection. The mucus they produce helps to trap pathogens and particles, ensuring smoother passage of materials through hollow organs and aiding in the overall functionality of the epithelial barrier.

Understanding the role of goblet cells is important in a veterinary context since they contribute to the health of various systems within animals. For instance, in the respiratory system, mucus helps keep the airways moist and traps foreign particles like dust and bacteria, reducing the risk of infection.

While squamous cells, ciliated cells, and columnar cells are important in other functions and structures within the epithelial tissue, they do not have the specific role of mucus production and storage that goblet cells embody. Squamous cells provide a protective barrier, ciliated cells are involved in moving mucus and other substances across epithelial surfaces, and columnar cells play various roles, including secretion and absorption. However, none of these types are specialized for the manufacture of lubricating mucus as goblet cells are.
