In which part of the body are goblet cells primarily found?

Goblet cells are specialized epithelial cells primarily found in the lining of the intestines and respiratory tracts. Their main function is to secrete mucus, which serves to lubricate and protect the epithelial surfaces. In the intestines, mucus produced by goblet cells plays a vital role in facilitating the passage of food and waste, as well as providing a barrier against pathogens and aids in the digestion process.

While goblet cells can also be present in other areas, such as the respiratory tract, their primary association in the context of an anatomy and physiology course for vet technicians is with the intestines. Understanding the function of goblet cells and their locations helps to illustrate the importance of mucus in both digestive health and the overall protective mechanisms of various tissues in the body.
