Question

Which cells in the small intestinal mucosa secrete mucus?

Answer 1

The cells in the small intestinal mucosa that secrete mucus are the Goblet cells. These cells are also found in other parts of the body such as the bronchi, trachea, larger bronchioles, large intestines and the conjuctiva in the upper eyelid where they are responsible for secreting mucin in tears. In the small intestine mucosa they secrete mucus that  ease the movement of feces and also protects the intestine from the corrosion by acids and gases produced by enteric bacteria.
