Goblet Cells - GCSE Biology Definition

Goblet cells are special cells found in the lining of the respiratory and digestive systems, like the airways and intestines. They are called "goblet" cells because they are shaped a bit like a goblet or cup. Their main job is to produce and release mucus, a thick, sticky liquid. This mucus helps protect the lining of these parts of the body by trapping dust, bacteria, and other unwanted particles, stopping them from getting deeper into the body. In the airways, mucus keeps the passages moist and helps us breathe more easily, while in the intestines, it supports the smooth movement of food. Goblet cells play an important role in keeping our bodies safe and healthy by lining these important systems with a protective barrier.
