Goblet cells can be found in the epithelium of the small and large intestines. These cells secrete mucus to make food pass more easily through the digestive tract.
Goblet cells look like little goblets and lie scattered between the absorptive cells in the bowels. They are categorized as glandular epithelial cells. Goblet cells are examples of unicellular glands in the human body. The number of goblet cells increases farther down the digestive tract. At the upper end of the digestive tract, in the first portion of the small intestine called the duodenum, the number of absorptive cells greatly outnumber the number of goblet cells. The colon contains a larger percentage of goblet cells than the small intestine.
