Goblet cells a level biology
WebGoblet cells are a secretory epithelial cell lineage found in both the small and the large intestines. A major function of goblet cells is the production of mucus, which forms a protective gel-like layer over the surface epithelium and protects against bacterial invasion (Johansson et al., 2008) (discussed in detail in Section 4 ). WebGoblet cells can be found scattered throughout the ciliated epithelium in the trachea They are mucus-producing cells that secrete viscous mucus which traps dust, bacteria and …
