Quizplus · Accepted Answer

Prostaglandins help increase the production of mucus and bicarbonate, which protect and maintain the integrity of the gastric mucosa, thus protecting it from damage caused by acid and other irritants. Aspirin, on the other hand, is known to cause damage to the gastric mucosa. Helicobacter pylori is a bacterium that can cause gastric ulcers and damage to the mucosal barrier. Regurgitated bile can also contribute to the erosion of the gastric mucosa.
