Which of the following cells secrete mucus in the alimentary canal?

Goblet cells are specialised columnar epithelial cells found throughout the epithelial lining of the alimentary canal, particularly in the stomach and intestines. They produce and secrete mucus, a viscous and protective substance that lubricates and protects the lining of the digestive tract. Mucus helps to moisten and protect the epithelial cells from mechanical damage, chemical irritation, and microbial invasion. This secretion aids in the smooth passage of food along the digestive tract and contributes to maintaining the health of the gastrointestinal mucosa.
