Prostaglandins and mucous cells both play a role in maintaining the body's defense barriers against ulcer formation. Prostaglandins protect the stomach lining by inhibiting acid secretion and promoting mucus secretion, while mucous cells produce mucus that forms a barrier between the stomach lining and gastric acid. Stomach pH and hydrochloric acid actually contribute to ulcer formation, and intrinsic factor plays a role in vitamin B12 absorption but is not directly related to ulcer prevention.
