Final answer:
An erosion in the lining of the stomach caused by an irritant can lead to an ulcer, most commonly resulting from an infection with Helicobacter pylori. Avoiding foods that increase stomach acid or irritate the stomach lining can help prevent ulcers. Peptic ulcers include gastric and duodenal ulcers, which can be caused by various factors including bacteria and medication.
Step-by-step explanation:
An irritant can cause an erosion in the lining of structure C, leading to a disorder known as an ulcer. When the mucus lining of the stomach ruptures and does not reform, an open wound is formed, which may be caused by the bacterium Helicobacter pylori. Ulcers can be prevented by eliminating items that aggravate the stomach and increase its acid content, which in turn can degrade the mucus lining and contribute to ulcer formation.
A peptic ulcer is a specific term for ulcers in the lining of the stomach or duodenum. The most common cause of peptic ulcers is infection with Helicobacter pylori. Lifestyle factors and the use of nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin can also contribute to the development of peptic ulcers.
