Mucous cells of the stomach lining secrete mucus (pink) into the lumen. In vertebrates, mucus (/mjuËkÉs/ MYOO-kÉss; adjectival form: mucous) is a slippery secretion produced by, and covering, mucous membranes. Mucous fluid is rich in glycoproteins and water and is typically produced from cells found in mucous glands.
What is the mucus plug? The mucus plug is a thick layer of mucus that lodges in the cervical opening to act as the last line of defense against infection entering the uterus via the birth canal. It protects the uterus and growing baby from bacterial infection.
