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.
Mucolytics are medicines that thin mucus, making it less thick and sticky and easier to cough up. They are used to treat respiratory conditions characterized by excessive or thickened mucus, such as a chesty (productive) cough.
