Quizplus · Accepted Answer

Prostaglandins modulate the secretion of mucin, bicarbonate, and proteoglycans, which are all protective factors for the gastric mucosa. One of the functions of proteoglycans is to provide a barrier to acid diffusion, thereby protecting the stomach lining from the effects of low pH. Prostaglandins also help maintain blood flow to the stomach lining, which is important for its integrity.
