What is the function of goblet cells?

Goblet cells are specialized cells found in the lining of the respiratory and digestive tracts that secrete mucus. The mucus produced by goblet cells helps to protect and lubricate the lining of these organs, trapping and removing foreign particles, pathogens, and other potentially harmful substances. This helps to prevent infections and maintain the health of the respiratory and digestive systems.

Goblet cells are unicellular glands found in the linings of the respiratory and digestive tracts. They secrete mucins, the main component of mucus. Mucus is a viscous fluid that helps to protect and lubricate the lining of these tracts. It traps dust, bacteria, and other foreign particles, and helps to move them out of the body. Goblet cells are also thought to play a role in immune defense.
