Final answer:
Inflammation of the gastric mucosa or submucosa can cause gastric ulcers, which are sores in the lining of the stomach.
Step-by-step explanation:
Inflammation of the gastric mucosa or submucosa can result in gastric ulcers. Gastric ulcers are sores that develop in the lining of the stomach. The pain of a gastric ulcer is partially due to irritation of the ulcerated tissue by acidic gastric juice. Infections and intoxications of the gastrointestinal tract can cause other conditions like gastroenteritis, but they are not specifically related to inflammation of the gastric mucosa or submucosa.
