In the term gastroduodenitis, what do the parts gastr/o and duoden/o refer to?

Explanation:
The main idea is understanding medical roots: gastr/o (or gastro-) means the stomach, and duoden/o refers to the duodenum, the first section of the small intestine just after the stomach. In gastroduodenitis, inflammation is in both of these parts—the stomach and the duodenum. The other options point to the colon (large intestine), jejunum (another part of the small intestine after the duodenum), or the liver, which aren’t the structures named by these roots.
